The Grand Tour

Ok, this is short! The long version of what PYTHEAS is all about is here. The searching is fairly straightforward but not all of the options presented are available yet. The "namespace" option on the RDF form references a BIB1 scheme that hasn't been mapped yet. Both the RDF and MARC form can be "grown" as needed, just pick the boolean operator at the end of the line and hit the "Next" button. The "left" and "right" truncation options are blissfully ignored at this point for RDF searches, and all RDF results come back as XML. You can see how the queries are mapped and Google's suggestions (if any) in the comments on the top.

MARC searching brings back bibliographic records and the results are converted to HTML using a simple stylesheet. I would like to add an option to bring back just the MARC fields with matches, and use lazy loading instead of bringing back the entire search set. The full mapping is available here, and the sql for creating the MySQL implementation is here, and the Hypersonic SQL setup is here. Names, Subjects, and Ontologies use "many-to-many" relationships, this isn't reflected in the current servlet but is in the pipeline.

The RDF mappings need lots of explanation, and the inference possibilities need some scrutiny. More to come...
