DataRSS

The latest issue of Nodalities has an interesting article, Anatomy Of A SearchMonkey by Peter Mika. It is a run-down of Yahoo's new Semantic Web search platform. The part that interested me was a flavor of ATOM, DataRSS.
These considerations led to the development of DataRSS, an extension of Atom for carrying structure data as part of feeds. A standard based on Atom immediately opens up the option of submitting metadata as a feed. Atom is an XML-based format which can be both input and output of XML transformation. The extension provides the data itself as well as metadata such as which application generated the data and when was it last updated.

Cataloger’s Desktop Enhancement

LC has announced "The Cataloging Distribution Service (CDS) is pleased to announce that its flagship online cataloging documentation resource, Cataloger’s Desktop, has been enhanced to include OCLC’s Bibliographic Formats and Standards." About time.

MoinMoin Wiki Syntax for Description Set Profiles

The Dublin Core folks have a draft, A MoinMoin Wiki Syntax for Description Set Profiles
This document describes a MoinMoin wiki syntax for a Description Set Profile as defined in the DCMI Working Draft "Description Set Profiles: A constraint language for Dublin Core Application Profiles" of March 2008 [DC-DSP], which in turn is based on the DCMI Abstract Model [ABSTRACT-MODEL]. It is recommended to have some understanding of the concepts of Description Set Profile (abbreviated DSP in the rest of this document) before reading this document.

A DSP is a way of describing structural constraints on a description set and is not directly intended for human consumption. However, with the wiki syntax for DSPs described here, it is possible to mix normal wiki syntax with DSP-specific wiki syntax in order to document an Application Profile. This means that from the same source it is possible to create:

  • A Dublin Core Application Profile that contains wiki syntax for a Description Set Profile, but is rendered as an HTML page for human consumption
  • A formal serialization in XML for the same Description Set Profile, used for machine (computer) consumption.
Once again the DCMI Abstract Model is a basis for the document (like RDA), have to get to know it better.
