    Abstract
    This is a report on how Doyle and others made a faceted classification scheme for content management systems and made it browsable on the web (see CMS Review in Example Web Sites, below). They discuss why they did it, how, their use of OPML and XFML, how they did research to find terms and categories, and they also include their taxonomy. It is interesting to see facets used in a business environment.

    Abstract
    Networked orientated standards for vocabulary publishing and exchange and proposals for terminological services and terminology registries will improve sharing and use of all knowledge organization systems in the networked information environment. This means that documentary classifications may also become more applicable for use outside their original domain of application. The paper summarises some characteristics common to documentary classifications and explains some terminological, functional and implementation aspects. The original purpose behind each classification scheme determines the functions that the vocabulary is designed to facilitate. These functions influence the structure, semantics and syntax, scheme coverage and format in which classification data are published and made available. The author suggests that attention should be paid to the differences between documentary classifications as these may determine their suitability for a certain purpose and may impose different requirements with respect to their use online. As we speak, many classifications are being created for knowledge organization and it may be important to promote expertise from the bibliographic domain with respect to building and using classification systems.

    Abstract
    Das in den letzten Jahren wiedererwachte Interesse an der klassifikatorischen Erschließung und Recherche hat sich allem Anschein nach noch nicht ausreichend bis zu den Herstellern integrierter Bibliothekssysteme herumgesprochen. Wie wäre es sonst zu erklären, dass im OPAC-Modul eines führenden Systems wie Aleph 500 so gut wie keine Features für klassifikationsbasierte Recherchen zu erblicken sind? Tatsächlich finden wir heute einen im Vergleich zum einstigen System Bibos kaum veränderten Zustand vor: Notationen eines oder mehrerer Klassifikationssysteme können in einer durch MAB dafür bestimmten Kategorie (700, nebst Indikatoren) katalogisiert und dann recherchiert bzw. angezeigt werden. Doch welcher Benutzer weiß schon, was diese Notationen im einzelnen bedeuten? Wer macht sich die Mühe, dies selbst herauszufinden, um dann danach zu recherchieren? Hier liegt im wesentlich dasselbe Problem vor, das schon dem systematischen Zettelkatalog anhaftete und ihn zu einem zwar mühevoll erstellten, aber wenig genutzten Rechercheinstrument machte, das nur dann (zwangsläufig) angenommen wurde, wenn ein verbaler Sachkatalog fehlte. Nun könnte eingewandt werden, dass im Vergleich zu früher unter Aleph 500 wenigstens das Aufblättern von Indizes möglich sei, sodass im OPAC ein Index für die vergebenen Notationen angeboten werden kann (bzw. mehrere solche Indizes bei Verwendung von mehr als nur einem Klassifikationssystem). Gewiss, doch was bringt dem Uneingeweihten das Aufblättern des Notationsindex - außer einer alphabetischen Liste von kryptischen Codes? Weiter könnte man einwenden, dass es im Aleph-500-OPAC die so genannten Suchdienste ("services") gibt, mithilfe derer von bestimmten Elementen einer Vollanzeige hypertextuell weiternavigiert werden kann. Richtig, doch damit kann man bloß wiederum den Index aufblättern oder alle anderen Werke anzeigen lassen, die dieselbe Notationen - also einen Code, dessen Bedeutung meist unbekannt ist - aufweisen. Wie populär mag dieses Feature beim Publikum wohl sein? Ein anderer Einwand wäre der Hinweis auf das inzwischen vom Hersteller angebotene Thesaurus-Modul, das vermutlich auch für Klassifikationssysteme eingesetzt werden könnte. Doch wie viele Bibliotheken unseres Verbundes waren bisher bereit, für dieses Modul, das man eigentlich als Bestandteil des Basissystems erwarten könnte, gesondert zu bezahlen? Schließlich mag man noch einwenden, dass es im Gegensatz zur Bibos-Zeit nun die Möglichkeit gibt, Systematiken und Klassifikationen als Normdateien zu implementieren und diese beim Retrieval für verbale Einstiege in die klassifikatorische Recherche oder zumindest für die Veranschaulichung der Klassenbenennungen in der Vollanzeige zu nutzen. Korrekt - dies ist möglich und wurde sogar einst für die MSC (Mathematics Subject Classification, auch bekannt als "AMS-Klassifikation") versucht. Dieses Projekt, das noch unter der Systemversion 11.5 begonnen wurde, geriet jedoch nach einiger Zeit ins Stocken und fand bedauerlicherweise nie seinen Weg in die folgende Version (14.2). Mag auch zu hoffen sein, dass es unter der neuen Version 16 wieder weitergeführt werden kann, so weist dieses Beispiel doch auf die grundsätzliche Problematik des Normdatei-Ansatzes (zusätzlicher Aufwand, Kontinuität) hin. Zudem lohnt sich die Implementierung einer eigenen Normdatei 4 wohl nur bei einem größeren bzw. komplexen Klassifikationssystem, wogegen man im Falle kleinerer Systematiken kaum daran denken würde.

    Abstract
    Examines ho well UDC numbers performs as a subject retrieval device in online systems. Discusses: truncation, coordination, USC as a discipline based scheme, ranges, and requirements in search software. Gives examples of UDC in pre-coordinated and post-coordinated working systems. Discusses the possible use of UDC as a thesaurus. Outlines improvements that would enable its use in online retrieval

    Abstract
    Summarizes some experiences of the application of the priciples and postulates of S.R. Ranganathan's General Theory of Knowledge Classification, incorporating the freely faceted approach and analytico synthetic methods, to the design and development of specialized databases, including indexing, user interfaces and retrieval. Enumerates some of the earlier instances of the facet method in machine based systems, beginning with Hollerith's punched card system for the data processing of the US Census. Elaborates on Ranganathan's holistic approach to information systems and services provided by his normative principles. Notes similarities between the design of databases and faceted classification systems. Examples from working systems are given to demonstrate the usefulness of selected canons and principles of classification and the analytico synthetic methodology to database design. The examples are mostly operational database systems developed using Unesco's Micro CDS-ISIS software

    Abstract
    The paper analyses the importance of data presentation and modelling and its role in improving the management, use and exchange of analytico-synthetic classifications in automated systems. Inefficiencies, in this respect, hinder the automation of classification systems that offer the possibility of building compound index/search terms. The lack of machine readable data expressing the semantics and structure of a classification vocabulary has negative effects on information management and retrieval, thus restricting the potential of both automated systems and classifications themselves. The authors analysed the data representation structure of three general analytico-synthetic classification systems (BC2-Bliss Bibliographic Classification; BSO-Broad System of Ordering; UDC-Universal Decimal Classification) and put forward some core requirements for classification data representation
