LDP Support
The following is a list of the salient ways Fedora 4 supports LDP:
- The web interface shows LDP relations under the children section for a resource.
- Fedora 4 supports all LDP containers.
- Fedora 4 uses LDP terminology to describe resources and associated properties (e.g. Glossary and http://www.w3.org/ns/ldp#containsldp#contains).
- LDP compliance is checked via invoking LDP Test Cases. Fedora 4 integration tests rely on the specification provided LdbTestSuite library for verification. Properties of a resource can be selected via XPath-style LDPath queries.
The main LDP-related implementation resides in the fcrepo-kernel and fcrepo-kernel-impl modules. Transforms are provided by the Apache Marmotta LDPath library.
