- Abstract
- In 2003, OCLC published Dewey Decimal Classification and Relative Index, Edition 22 (DDC 22), in print and Web versions. The changes and updates in the new edition reflect a modern view of knowledge structures and address the general needs of Dewey users. The content of DDC 22 has been shaped by a number of social, geopolitical, and technical trends. The World Wide Web has provided a vehicle for more frequent distribution of updates to the DDC, and a medium for direct communication with Dewey users around the world. In addition to updating the system itself, other strategies are needed to accommodate the needs of the global Dewey user community. Translation of the system is one approach; another is mapping. Mapping terminology to the DDC is a strategy for supporting effective local implementation of the system while maintaining the internal cohesiveness of the DDC. This paper explores the usefulness of mapping terminology from English-language general subject headings lists produced outside the U.S.

- Abstract
- The paper will give a short outline of the project DDC German. The project is not limited to a mere translation of DDC 22, but aims at the implementation of Dewey in the library networks of the German-language countries. Use of DDC mainly for retrieval purposes, not for shelving, leads to certain new aspects in classifying with Dewey which are described in detail and presented together with the German web service Melvil. Based an the German experience of cooperation and data exchange in the field of verbal indexing the paper develops some ideas an future Dewey cooperation between European and American libraries.

- Abstract
- The Library of Congress Classification (LCC), originally designed for classifying the Library's own collection, is now used in a wide range of libraries, both in the United States and abroad. This entry recounts its history and development from its genesis to the present time, leading up to an explanation of LCC structure, tables, and notation. It then considers the system's potential for wider application in the online age, through speculation on using LCC as a tool for (a) partitioning large files; (b) generating domain-specific taxonomies; and (c) integrating classification and controlled subject terms for improved retrieval in the online public access catalog (OPAC) and the Internet. Finally, analyzing both its strong and relatively weak features, it addresses the question of whether in its current state LCC is in all respects ready for playing such roles

- Abstract
- To those outside the field of library science, the name Melvil Dewey (1851-1931) is virtually synonymous with library classification. To those in the field, Dewey has been recognized as the premier classification maker. His enormously successful system (i.e., successful in terms of the wide adoption of the system around the world for over one hundred years) has now undergone nineteen editions. The Dewey Decimal Classification has been translated into more than twenty languages and is the most widely adopted classification scheme in the world. Even in its earliest manifestations, the Dewey Decimal Classification contained features that anticipated modern classification theory. Among these are the use of mnemonics and the commonly applied standard subdivisions, later called "common isolates" by S. R. Ranganathan (q.v.), which are the mainstays of facet analysis and synthesis. The device of standard subdivisions is an indication of the recognition of common aspects that pervade all subjects. The use of mnemonics, whereby recurring concepts in the scheme are represented by the same notation, for example, geographic concepts and language concepts, eased the transition of the Dewey Decimal Classification from a largely enumerative system to an increasingly faceted one. Another significant feature of the Dewey Decimal Classification is the use of the hierarchical notation based an the arabic numeral system. To a large extent, this feature accounts for the wide use and success of the system in the world across language barriers. With the prospect of increasing online information retrieval, the hierarchical notation will have a significant impact an the effectiveness of the Dewey Decimal Classification as an online retrieval tool. Because the notation is hierarchical, for example, with increasing digits in a number representing narrower subjects and decreasing digits indicating broader subjects, the Dewey Decimal Classification is particularly useful in generic searches for broadening or narrowing search results. In the preface to the second edition of his Decimal Classification Dewey explained the features of his "new" system. The excerpt below presents his ideas and theory concerning the rational basis of his classification, the standard subdivisions, the hierarchical notation based an decimal numbers, the use of mnemonics, the relative index, and relative location. It also reflects Dewey's lifelong interest in simplified spelling.

- Abstract
- This paper aims at exploring the changes in the role and representation of information retrieval languages, particularly the UDC system in the digital, online environment and the Internet. The Totalzoom Technology takes a different approach, with the help of which even a lay user can easily navigate in the "informational space". This system follows the free associative nature of human thinking. Technically, it works with the wide degree of freedom afforded by a logical-associative network, coupled with a hierarchical search tree as an inner auxiliary structure.

- 1. Introduction The use of classical classification methods are a strong tradition in Hungary. One of the most widespread systems is the Universal Decimal Classification (UDC). We can find it in every type of library and at various levels. Perhaps it is not an overstatement to say that every library has used the UDC at least once in its history, and most of them still use it. Such standardization has been very wide and desirable, although the UDC has not become as popular a system among users everywhere as it has in Hungary. Naturally there are other information retrieval languages, too. They have been used by many libraries, but generally these institutions build their own subject system, own thesaurus, etc. There have also been attempts at creating a Hungarian General Subject s, like a Library of Congress Subject Headings or Regeln für den Schlagwortkatalog. Another project was the KÖZTAURUSZ (Comprehensive Thesaurus for the Public Libraries) and the National Széchényi Library's thesaurus. To what do we owe such a variety of approaches? The typical answer of 15-20 years ago was that the UDC lacked flexibility, its codes could not readily be used in integrated library systems, its terms were out of date and not concrete enough, etc.

- Abstract
- Dewey Decimal Classification and Relative Index, Edition 22 (DDC 22) will be issued simultaneously in print and web versions in July 2003. The new edition is the first full print update to the Dewey Decimal Classification system in seven years-it includes several significant updates and many new numbers and topics. DDC 22 also features some fundamental structural changes that have been introduced with the goals of promoting classifier efficiency and improving the DDC for use in a variety of applications in the web environment. Most importantly, the content of the new edition has been shaped by the needs and recommendations of Dewey users around the world. The worldwide user community has an important role in shaping the future of the DDC.

- Abstract
- This paper presents the results of an exploratory study to determine literary warrant for topics in electronic resources. The classification numbers in Abridged Edition 14 were used as a starting point. Using the principles of abridgment and expansion in Dewey, a version of the DDC is defined that accommodates the topics found an three diverse Web sites that use Dewey: BUBL, Canadian Information By Subject, and KidsClick! The resulting classes are used to create a database for automated classification of Web resources.

- Abstract
- In the Internet information space, advanced information retrieval (IR) methods and automatic text processing are used in conjunction with traditional knowledge organization systems (KOS). New information technology provides a platform for better KOS publishing, exploitation and sharing both for human and machine use. Networked KOS services are now being planned and developed as powerful tools for resource discovery. They will enable automatic contextualisation, interpretation and query matching to different indexing languages. The Semantic Web promises to be an environment in which the quality of semantic relationships in bibliographic classification systems can be fully exploited. Their use in the networked environment is, however, limited by the fact that they are not prepared or made available for advanced machine processing. The UDC was chosen for this research because of its widespread use and its long-term presence in online information retrieval systems. It was also the first system to be used for the automatic classification of Internet resources, and the first to be made available as a classification tool on the Web. The objective of this research is to establish the advantages of using UDC for information retrieval in a networked environment, to highlight the problems of automation and classification exchange, and to offer possible solutions. The first research question was is there enough evidence of the use of classification on the Internet to justify further development with this particular environment in mind? The second question is what are the automation requirements for the full exploitation of UDC and its exchange? The third question is which areas are in need of improvement and what specific recommendations can be made for implementing the UDC in a networked environment? A summary of changes required in the management and development of the UDC to facilitate its full adaptation for future use is drawn from this analysis.

- Rez. in: Knowledge organization 31(2004) no.2, S.112-114 (M.P. Satija) : "With nearly 130 years of eventful and checkered history, the Dewey Decimal Classification (DDC) is the oldest living yet thriving modern library classification. Having undergone 21 revisions, it is the most applied library classification structure all over the world. Apart from its use in libraries in more than 135 countries across six continents, many national and trade bibliographies use it for content organization. Furthermore, it is now making successful forays into the world of electronic documents and networked information. The print version of the 22nd edition was released in September 2003, two months later than the scheduled time of July 2003, and two months after the release of the electronic version, WebDewey. The period between print editions now seems settled to seven years as a matter of policy. As WebDewey, an the other hand, is updated an a quarterly basis, what really constitutes a new edition is problematic; edition is rolling, always in a flux without much fixity. The last half century, and more specifically the tenure of Benjamin A. Custer as editor (1956-1980; Editions 16-19), has been an era of structural changes in the DDC, backed by professional management and organizational planning. Custer was instrumental in not only resuscitating the system, but also in putting DDC back an the path of progress. His able successor, Dr. John P. Comaromi, edited the 20`h edition (1989) and ushered in a period of simplification and consolidation. Following the acquisition of Forest Press by OCLC in 1988, much more research has gone into making new editions of the DDC. The OCLC Office of Research has involved itself in classification research, especially in the harmonization of various knowledge classification systems and mapping of DDC numbers to subject headings, above all to make DDC capable of organizing electronic information of every sort. The acquisition of DDC by OCLC has also inaugurated an era of new products and services, along with organized marketing. DDC21 (1996) was a product of high IT, and the 22nd edition can safely be termed a child of network technology. It is indeed the first edition produced in the web environment. To stay abreast of current developments an knowledge practices, the editors relied an the Internet and electronic databases for new topics and terms. Editors and policy makes got constant feedback and suggestions via the Internet to add new features and to achieve accuracy and efficiency. In addition to the feedback and expert advice, this edition, as usual, is based an actual classification of three quarters of a million current books in the Decimal Classification Division of the Library of Congress since 1996.
Changes DDC22 is the second edition prepared by Joan S. Mitchell who took over as editor in 1993. It carries forward the policies and improvements started in DDC21, especially the onslaught an the Christian and western cultural blas in the schedules and tables. The plan for reducing Christian blas in 200 Religion, initiated in DDC21, has now been completed, with some additional provisions in 296 and 297. An outstanding change has been the abrogation of Table 7 Persons. The functions of Table 7 are now filled by using T1-08 and whatever notation is appropriate from 011-999. There are at least six places in the tables and 12 places in the schedules where the use of T7 was prescribed; what good the abolition of T7 has produced is not clear. In fact, it does make number building in some cases a bit circuitous, especially while using Table 3C. It has also resulted in the reuse of many DDC 21 numbers with new meanings. However, some numbers remain the same e.g., Social customs of artists 390.47 (both in DDC21 and DDC22). A few numbers have also become shorter in length. In compliance with the recommendations of D'Elia's survey, all works relating to directories of travel facilities such as hotels, lodges, Motels, inns, have been shifted to 910.46 and to 913/919 whereas 647.94 continues to be in place for general information about hotels. A common practice in previous editions, that is full class or extensive revisions (phoenix schedules), appear to have been discontinued in the preparation of DDC22. But minor changes are numerous. There are more than one thousand relocations and discontiuations of class numbers. Some 40 numbers have been reused. ... However, all these changes are not those projected as slated changes for DDC22 in the DDC21 (1996), namely in 520 Astronomy, 355-359 Military science, 636-639 Animal husbandry and 690 Buildings. Obviously the switch over to the DDC 22 will put less strain an libraries. There has been considerable improvement in the manual, now shifted to volume 1 of the print edition (pp. 1-182). Notes in the manual have been shortened by removing redundant information and by dividing them into smaller sections. Some information from the manual has been transferred to the schedules and tables, in the form of notes. The manual is now clearer and easier to read. Flow Charts, built-in numbers, and see also references should help classifiers achieve greater consistency. The relative index has been beefed up. With its 928 pages, it is 333 pages longer than the previous one, including new built-in numbers and many additional terms. The entry vocabulary is wide-based and current. DDC 22, the first edition of this millennium, has kept pace with the fast changing information environment to map and organize it squarely. To quote our friends at OCLC: knowledge is a big world, and they have organized it."

- Abstract
- Die Dewey-Dezimalklassifikation (DDC) ist Ende 2003 in der 22. Ausgabe der Standard Edition auf Englisch erschienen und wird genau zwei Jahre später nun auch auf Deutsch veröffentlicht. Nach Übersetzungen ins Französische, Italienische, Russische und Spanische ist unter Beteiligung der drei deutschsprachigen Länder und mit Unterstützung durch die Deutsche Forschungsgemeinschaft die Voraussetzung dafür geschaffen worden, dass diese international weit verbreitete Klassifikation auch in Deutschland, Österreich und der Schweiz heimisch werden kann. Die hier vorgelegten Übersichten, die die drei obersten Ebenen oder 1 000 Klassen der DDC umfassen, ermöglichen einen Einblick in die Gliederung der gesamten Klassifikation und sind in dieser Form für Bibliotheken und wissenschaftliche Einrichtungen frei verfügbar, während die tieferen Ebenen der DDC durch das Urheberrecht geschützt sind. Die vollständige Ausgabe der DDC 22 Deutsch erscheint 2005 im Verlag K. G. Saur. Mit dem Webservice Melvil bietet Die Deutsche Bibliothek ab Januar 2006 eine deutsche Version von WebDewey an, ergänzt um ein Recherchetool für das Retrieval DDC-erschlossener Daten. Die DDC 22 ist von einer an der Fachhochschule Köln angesiedelten Arbeitsgruppe ins Deutsche übersetzt worden, unterstützt von einemTeam von Fachreferentinnen und Fachreferenten an zahlreichen Bibliotheken des deutschen Sprachraums und fachlich beraten von der Expertengruppe DDC Deutsch. Die organisatorische Leitung des Projekts DDC Deutsch lag bei Der Deutschen Bibliothek als federführendem Mitglied des Konsortiums DDC Deutsch. Ab 2006 wird die Deutsche Nationalbibliografie vollständige DDC-Notationen mitliefern, bereits seit Bibliografiejahrgang 2004 folgen die Sachgruppen der Deutschen Nationalbibliografie einer auf den beiden obersten Ebenen der DDC basierenden Gliederung. Die hier vorgelegte Übersetzung der DDC wurde mit der Herausgeberin der DDC, Joan Mitchell (OCLC, Dublin/Ohio) und ihren Mitherausgebern an der Library of Congress abgestimmt, denen wir für ihre Unterstützung und Beratung herzlich danken. Die kurze Einführung in die Dewey-Dezimalklassifikation, die hier folgt, stellt das gesamte System der DDC vor, das mit seinen Haupt- und Hilfstafeln mehr als 60 000 Klassen umfasst. Die Möglichkeiten zur Erschließung differenzierterThemen gehen daher weit über die hier vorgelegten obersten Klassen der DDC hinaus und berücksichtigen viele moderne Teildisziplinen, die man in den Übersichten vielleicht vermisst. Bei der Verwendung der Übersichten ist zu beachten, dass aus drucktechnischen Gründen in einigen Fällen Klassen nur verkürzt wiedergegeben werden können und nur durch ihre Position innerhalb einer Folge von Klassen genau zu verstehen sind. Daher sollten für die Erschließung auch die vollständigen Klassenbenennungen herangezogen werden, die unter www.ddc-deutsch.de im Netz zur Verfügung stehen.

- Abstract
- The paper will look into different patterns of facet analysis used in the UDC schedules and how these affect the scheme presentation, the underlying data structure and the management of the classification scheme. From the very beginning, UDC was designed to represent the universe of knowledge as an integral whole allowing for subjects/concepts from all fields of knowledge to be combined, linked and the nature of their relationships made explicit. In Otlet's original design, the emphasis for his new type of classification was on the coordination of classmarks at the point of searching, i.e., post-coordination, which he firmly rooted in an expressive notational system. While some UDC classes exhibit various patterns of facet analytical theory proper, others, although used in an analytico-synthetic fashion, follow less canonical structural patterns. The authors highlight the lack of connection made throughout the various stages of UDC restructuring between: a) theoretical requirements of an overarching facet analytical theory as a founding principle guiding the construction of schedules; and, b) practical requirements for an analytico-synthetic classification in terms of notational presentation and data structure that enables its use in indexing and retrieval, as well as its management online.

- Abstract
- Toward the end of the nineteenth century, Paul Otlet and Henri LaFontaine of Belgium initiated the compilation of an index to all recorded knowledge. Instead of an alphabetical file, they decided to adopt a classified arrangement. For the basis of such an arrangement, they turned to the Dewey Decimal Classification, a system which was gaining wide acceptance in American libraries. With permission secured from Melvil Dewey to expand the system to include details required for an indexing tool, Otlet and LaFontaine began developing what was to become the Universal Decimal Classification (UDC). Following the establishment of the Institut International de Bibliographie (IIB), later the Fédération Internationale de Documentation (FID), in 1895, work an the universal index and the classification scheme proceeded under its aegis. In 1905, the classification scheme was published as the Manuel du Répertoire bibliographique universel. While the initial, ambitious project of the universal index was abandoned, the classification scheme itself was widely adopted, particularly in special libraries in Europe. A second edition was published in 1927-1933 under the title Classification décimale universelle. The development and maintanance of the scheme continued with the support of the FID. In the course of its development, the UDC moved further and further away from its prototype, the Dewey Decimal Classification. One of the major differences between the two systems is the use of relators in UDC. The notation adopted by Melvil Dewey for his scheme is a hierarchical one; in other words, the notation reflects the hierarchical relationships among subjects. However, it does not display the relationships among the facets, or aspects, of a particular subject. Furthermore, the use of auxiliaries in the Dewey Decimal Classification, beginning with the form subdivisions and gradually expanding to include geographic subdivisions and finally other auxiliaries in the most recent editions, has been relatively restricted. As an indexing tool, Otlet and LaFontaine felt that their system needed commonly applicable auxiliaries which they called "determinatives."` To this end, a series of special symbols were introduced into the system for the purpose of combining related subjects and indicating different facets or aspects of the main subject. The use of these symbols, called relators, with the auxiliaries has rendered the Universal Decimal Classification a synthetic scheme. In this respect, the UDC has moved much more rapidly than the Dewey Decimal Classification toward becoming a faceted classification. In the following paper, Henry V. Hopwood, a Senior Assistant at the British Patent Office Library during the 1900s, explains the use and rationale of relators, or "marks," as he calls them, in the Universal Decimal Classification.

- Abstract
- The article discusses various aspects of the Dewey Decimal Classification (DDC) system of classifying library books in 2013. Background is presented on some librarians' desire to stop using DDC and adopt a genre-based system of classification. It says librarians can use the DDC to deal with problems and issues related to library book classification. It highlights the benefits of using captions and relative index terms and semantic relationships in DDC.
- Content
- "As knowledge brokers, we are living in interesting times for libraries and librarians. We wonder sometimes if our traditional tools like the Dewey Decimal Classification (DDC) system can cope with the onslaught of information. The categories provided don't always seem adequate for the knowledge-discovery habits of today's patrons. They have grown accustomed to new ways for their information needs to be met, from the fire-and-forget style of a hard-to-control classic Google search to the pervasive, always-on style of Google Now, anticipating users' information needs without their having even asked a verbal question. Contrariwise, I believe that we, as librarians, could be making better use of our tools. Many (like the DDC) are a reflection of the same social and epistemological forces that brought about modernity at the turn of the last century. We as librarians are in the unique position of providing services that are as ground-breaking as these tools. As we see the need to provide unique and cutting-edge knowledge discovery to our users, I argue in this article that the DDC can play a key role in fulfilling this purpose."

- Abstract
- Purpose - The purpose of this paper is to present a general overview with up-to-date information on the Universal Decimal Classification (UDC) use worldwide. Design/methodology/approach - The research combined e-mail interviews with LIS professionals in 208 countries, literature research and information obtained from UDC distributors/publishers (AENOR, BSI, UDC Consortium). The following categorisation of UDC use was offered: A - dominant system; B - used in some kind of libraries only; or C - rarely used. Findings - The paper finds that, of the 208 countries contacted and researched through the literature in 2004-2006, the UDC was found to be used in 124 (60 per cent) of these. In 34 (28 per cent) of the countries researched (in Europe, Asia and Africa), UDC is the main classification system used across national information networks. In 45 (36 per cent) of the countries it is used in certain kinds of libraries. In the remaining 45 (36 per cent) of the countries it is used rarely, in only a few libraries or information centres. Research limitations/implications - It was beyond the scope of this research to provide any information regarding the actual number of institutions using UDC in a given country or to give an estimate of the size and number of document collections organised by it. Although a decline in UDC use since the 1980s was reported from a number of countries, it was not possible to measure this accurately. Practical implications - The interest shown for using UDC in the organisation of digital collections, information exchange and cross domain and cross collection resource discovery depends on accurate knowledge of its actual usage worldwide. This gives a measure of its global importance and verifies its credentials as an indexing standard. This research, which attempted wider and more systematic coverage than previous surveys, should help clarify the status of UDC and its potential use in the networked environment. Originality/value - The paper provides up-to-date information on the presence of the UDC system across countries and languages.

- Abstract
- In this book, John Bowman provides an introduction to the Dewey Decimal Classification suitable either for beginners or for librarians who are out of practice using Dewey. He outlines the content and structure of the scheme and then, through worked examples using real titles, Shows readers how to use it. Most chapters include practice exercises, to which answers are given at the end of the book. A particular feature of the book is the chapter dealing with problems of specific parts of the scheme. Later chapters offer advice and how to cope with compound subjects, and a brief introduction to the Web version of Dewey.
- Content
- "The contents of the book cover: This book is intended as an introduction to the Dewey Decimal Classification, edition 22. It is not a substitute for it, and I assume that you have it, all four volumes of it, by you while reading the book. I have deliberately included only a short section an WebDewey. This is partly because WebDewey is likely to change more frequently than the printed version, but also because this book is intended to help you use the scheme regardless of the manifestation in which it appears. If you have a subscription to WebDewey and not the printed volumes you may be able to manage with that, but you may then find my references to volumes and page numbers baffling. All the examples and exercises are real; what is not real is the idea that you can classify something without seeing more than the title. However, there is nothing that I can do about this, and I have therefore tried to choose examples whose titles adequately express their subject-matter. Sometimes when you look at the 'answers' you may feel that you have been cheated, but I hope that this will be seldom. Two people deserve special thanks. My colleague Vanda Broughton has read drafts of the book and made many suggestions. Ross Trotter, chair of the CILIP Dewey Decimal Classification Committee, who knows more about Dewey than anyone in Britain today, has commented extensively an it and as far as possible has saved me from error, as well as suggesting many improvements. What errors remain are due to me alone. Thanks are also owed to OCLC Online Computer Library Center, for permission to reproduce some specimen pages of DDC 22. Excerpts from the Dewey Decimal Classification are taken from the Dewey Decimal Classification and Relative Index, Edition 22 which is Copyright 2003 OCLC Online Computer Library Center, Inc.

- Footnote
- "The title says it all. The book contains the essentials for a fundamental understanding of the complex world of the Dewey Decimal Classification. It is clearly written and captures the essence in a concise and readable style. Is it a coincidence that the mysteries of the Dewey Decimal System are revealed in ten easy chapters? The typography and layout are clear and easy to read and the perfect binding withstood heavy use. The exercises and answers are invaluable in illustrating the points of the several chapters. The book is well structured. Chapter 1 provides an "Introduction and background" to classification in general and Dewey in particular. Chapter 2 describes the "Outline of the scheme" and the conventions in the schedules and tables. Chapter 3 covers "Simple subjects" and introduces the first of the exercises. Chapters 4 and 5 describe "Number-building" with "standard subdivisions" in the former and "other methods" in the latter. Chapter 6 provides an excellent description of "Preference order" and Chapter 7 deals with "Exceptions and options." Chapter 8 "Special subjects," while no means exhaustive, gives a thorough analysis of problems with particular parts of the schedules from "100 Philosophy" to "910 Geography" with a particular discussion of "'Persons treatment"' and "Optional treatment of biography." Chapter 9 treats "Compound subjects." Chapter 10 briefly introduces WebDewey and provides the URL for the Web Dewey User Guide http://www.oclc.org/support/documentation/dewey/ webdewey_userguide/; the section for exercises says: "You are welcome to try using WebDewey an the exercises in any of the preceding chapters." Chapters 6 and 7 are invaluable at clarifying the options and bases for choice when a work is multifaceted or is susceptible of classification under different Dewey Codes. The recommendation "... not to adopt options, but use the scheme as instructed" (p. 71) is clearly sound. As is, "What is vital, of course, is that you keep a record of the decisions you make and to stick to them. Any option Chosen must be used consistently, and not the whim of the individual classifier" (p. 71). The book was first published in the UK and the British overtones, which may seem quite charming to a Canadian, may be more difficult for readers from the United States. The correction of Dewey's spelling of Labor to Labo [u] r (p. 54) elicited a smile for the championing of lost causes and some relief that we do not have to cope with 'simplified speling.' The down-to-earth opinions of the author, which usually agree with those of the reviewer, add savour to the text and enliven what might otherwise have been a tedious text indeed. However, in the case of (p. 82):

- Abstract
- Analytico-synthetic and faceted classifications, such as Universal Decimal Classification (UDC) provide facilities to express pre-coordinated subject statements using syntactic relations. In this case, the relevance, in the process of UDC-based information retrieval, can be determined by extracting the meaning of the classmarks as precisely as is possible. The central question here is how the identification mentioned above can be supported by automatic means and an analysis of the structure of complex classmarks appears to be an obvious requirement. Many bibliographic sources contain complex UDC classmarks which are stored as simple text strings and on which it is very difficult to perform any meaningful information discovery. The paper presents results from a phase of ongoing research focused on developing a new platform-independent, machine-processable data format capable of representing the whole syntactic structure of the composite UDC numbers to support their further automatic processing. An algorithm that can produce the representation of the numbers in such a format directly from their designations has also been developed and implemented. The research also includes implementing conversion methods to provide outputs that can be employed by other software directly and, as a service, make them available for other software. The paper provides an overview of the solutions developed and implemented since 2015 and outlines future research plans.
