BioWSR Code

* Added redland-describe.rb, which does not work because Redland
has a very poor implementation of 'DESCRIBE' SPARQL reserved word.
* wsrcore.rb is almost finished. It has suffered lots of changes.
IT IS NOT FUNCTIONAL YET, BECAUSE IT HAS NOT BEEN TESTED!!!!!!

* This sample code now takes two parameter: the input RDF, and optionally the serviceId,
which is used to store the RDF triples from each service in different contexts. When
the serviceId is not provided, the program returns the results from a global query
over all the graphs/contexts. When the serviceId is provided, the program returns
only the data from the matched graph, and it later removes its context in order to
show selective deletion.

* redland-contexts.rb shows how to put sets of triples in an specific context (concept from Redland).
This sample code is still unfinished, because it should also include a demonstration about removing
all the triples from a context.

* Added the chance to fetch the service status using SPARQL.

* Add 'LOG_RDF_ALIAS' constant

* Rename constant

* Improved redland-query.rb, which now it issues a much
more complex extraction query.

* redland-query.rb shows how to shred one RDF document into
several ones, store each one in a in-memory RDF database
and then query them using SPARQL.
* example-redirectHead.rb shows how to follow the redirection
status from the answers to HEAD requests.

* General documents that describe the system of BioWSR:
- GeneralizedRegistryURIs, describes the API and the format of the URIs and URNs understood by BioWSR, the generalized INB registry.
- INB_Document_Registry_WS_draft, describes how to retrieve the description of global web services created by INB.

* The extended RDF document that describes the INB services, has been processed using OWL ontology language.
* sampleAugmentedRDF.rdf, sample of service instance of augmented description of INB service.
