skos

Because SKOS is defined using the RDF model, it's easy to read and create data in an XML format.

The most important label is the preferred label, and SKOS allows each concept to have only one of these in each language.

Notice that there isn't always a one-to-one correlation between a SKOS concept and a construct in the XML vocabulary.

With SKOS, you manage concepts that have different kinds of labels, and each label might have a language associated with it.

SKOS-based tools for editing and managing your vocabularies should understand that extensibility is part of this standard.

You can also connect your data to a wider variety of data out there, whether it uses the SKOS ontology or not.

In the spectrum of standards, SKOS contributes by bridging the gap between traditional indexing and formal ontologies for the Semantic Web.

SKOS takes a higher-level view of what you manage, which makes internationalization much easier.

I also lift the SKOS concept description into the xs: documentation element, which helps smooth integration with WXS-aware tools.

Simple Knowledge Organization System (SKOS) provides a standard for indicating the subject matter of content.

Also, users of this DITA specialization should bear in mind that SKOS itself hasn't yet progressed to an approved standard.

Besides SKOS annotations, another useful Semantic Web practice in XML schema design is to use URIs for IDs.

Be careful because this article uses a slightly out of date version of SKOS.

In a typical approach, SKOS tools display the thesaurus or taxonomy to the user for browsing.

The skos: broader property is a way of organizing related concepts.

See Resources for full introductions to SKOS, but briefly, the first two lines are Turtle versions of namespaces declarations.

With SKOS, you can define relationships between concepts from different vocabularies.

SKOS is a good language to express the technical substance of such interchange.

Listing 1 is a subset of a SKOS definition of relevant concepts in Turtle syntax.

skos: definition is a brief but precise description of the concept.

However, SKOS provides a higher-level language that's designed for readable content.

skos: definition is a brief but precise description of what the concept is.

You will generally deal with XML versions of SKOS vocabularies in schemata.

Note: SKOS uses the concept label for these formal subjects.

As a result, the SKOS-compatible DITA specialization could undergo some evolution.

The constructs that come directly from the SKOS are in bold font.

The skos: broader property is a way to organize related concepts.

Listing 5 is a variation on Listing 3 using links to the SKOS rather than copying constructs.

iQvoc: Check out an open source tool for managing vocabularies that can import and export SKOS.

Concepts can have many kinds of relationships in SKOS besides "broader than. "

As specified by SKOS and implemented in the DITA specialization, a subject classification has the following parts
