Resources for Writing Fragment Identifiers ("Writing Fragids," WFs), a fragid scheme for URIs that designate text-bearing objects or written works.
Writing Fragids are intended for allow someone to take a URI that refers to a book, an article, or some other writing that is citable, and add a fragment to it, to specify a specific part. Such URIs are meant to be meaningful independent of any particular digital resource or media type, if it even exists.
For example, to refer to Walter Burkert's Lore and Science in Ancient Pythagoreanism, page 14 line 2, one may write:
http://www.worldcat.org/oclc/860129739#$wf0:a=w;t=m;r=.;14.2$
This URI can then be used in a variety of RDF statements. See the resources below for more examples and possible uses.
- Draft specifications: Docbook (master), PDF - introduction to WF URIs, with theoretical underpinnings, syntax definitions, and conformance requirements for media types and processors.
- WF functions - a non-normative function library in XSLT; includes a WF URI parser
- WF examples - examples of WF URIs in a variety of works and scripta
- Oxygen project, for managing the project, handling common tasks via Oxygen XML Editor.
The subdirectory tests contains XSpec resources to test the conformance suite; schemas contains schemas for various resources.
Other subdirectories such as TEI and TAN are, or will be, populated with resources illustrating how a media type can develop its on WF conformance specifications.
Writing Fragids are an experimental technology. The specifications are currently being explored, developed, and tested. Discussions for WFs are being conducted by Joel Kalvesmaki as a part of W3C's LD4LT community group in a subcommittee devoted to consolidating Linked Open Data vocabulary for linguistic annotations.
