Re: what are you using literal property values for?

Bill:

Sorr y for the delay in getting back to your request for info about
literals. I posted an announcement to the RDF Interest list a couple of
weeks ago (see below) about a new DOI service that uses RDF as the data
model to support intelligent resolution of a public identifier (the DOI -
Digital Object Identifier - currently being used by the STM publishing
community) to multiple resources. In this model a core set of properties is
defined to qualify (or specialize) the resources so that they can be
meaningfully interpreted by client applications. Literals are used for
these properties, which include: "access", "detail", "label", "resolve",
"role", and "type". For more information see

     http://www2.harcourt-international.com/~tony/doi/yads/DObject.html
or
     http://dx.doi.org/1014/yads [link from "Schematic Overview"]

Also of interest may be the use of a "data:" URI scheme (RFC 2397) to
support literals as resources in their own right, ie inline (or by-value)
resources rather than the usual by-reference resources.

Regards,
Tony

Many thanks for this - very timely. I already included support for the RDF
Validator into "yads" - Yet Another DOI Service. A DOI is a managed
identifier of an intellectual property entity which enables the network
retrieval of a set of related services. (For further information see <
http://dx.doi.org/10.1000/1>.) "yads" shows how DOIs can be simply resolved
to multiple resources and crucially how those resources are themselves
interrelated.

"yads" supports a number of visualizations of a DOI (menu popup, text dump,
and RDF arcs and nodes diagram courtesy of the RDF Validator), as well as
providing technical details of implementations.

"yads" is available at

     http://dx.doi.org/1014/yads

Hi,

I'm looking to scare up use cases folk have for RDF literals
as property values or indeed if anyone out there is using
literals in this way in applications or data models. Mainly
I'm curious to know:

- -what list members are using literals values for.
- -what kind of literals you are using (strings, xml/infoset,
binary...).
- -how applications are interpreting these literals.
- -if people are extending the parseType attribute.
- -what problems you're running into with literal values.

If you post to me directly, I'll summarize for the list.

Thanks,
Bill de hÓra
