This is a general dumping ground of small utility code reused across projects.

Caveats

Includes a lot of historical cruft which has been obsoleted by evolution of Jena.

Only documentation is the code and javadoc.

Main starting points

  • RDFUtil Collection of utilities for common trivial RDF tasks, a couple of other utils in that directory might be handy but most are obsoleted

  • Wrappers Provides wrappers for Datasets, Models and RDFNodes which simplify their use from scripting languages like Velocity. Obsoleted by appbase.

  • json Some utils for working with Jena's json support including a hacked version of the Talis-format RDF writer which handles lists as JSON arrays.

  • vocabs Schemagened versions of some common vocabularies, currently static rather than built form source. Should migrate to using maven schemagen plugin.

  • FileUtil Some utilities for creating directories and copying files

  • NameUtils String bashing functions used when encoding names in http calls etc

  • PrefixUtils Utilities for working with prefix mappings including merging and using them to expand SPARQL queries (pure string bashing level)

  • tasks Support for incremental reporting of messgaes from async processes, e.g. used for reporting data converter process to an ajax web UI

  • marshalling Set of JAX-RS bindings for read/write of RDF when using Jersey. This does mean that lib depends on Jersey which isn't nice. Could factor this out into the libraries that more naturally need Jersey anyway.

  • geo Support for geolocations including parsing/formating OS Grid References and converting to from lat/log (in WGS84 as well as OSGB36)

* [Abstract Sparql Query](https://github.com/epimorphics/lib/wiki/Abstract-Sparql-Query) Support

for an abstract SPQRAL query object that can be manipulated and then rendered into SPARQL text.

* [GeoQuery for ASQ](https://github.com/epimorphics/lib/wiki/GeoQuery-for-Abstract-Sparql-Query) 
Abstract GeoQuery objects for rendering into Abstract Sparql Queries.


* [text search for abstract sparql queries](https://github.com/epimorphics/lib/wiki/abstract-sparql-query-text-search)
