Package | Description |
---|---|
com.bigdata.bfs |
This package provides a scale-out content repository (aka distributed file
system) suitable as the backend for a REST-ful service using the bigdata
architecture.
|
com.bigdata.bop |
This package provides an API for query operators.
|
com.bigdata.bop.ap | |
com.bigdata.rdf.lexicon | |
com.bigdata.rdf.spo |
This package defines a statement model using long term identifiers rather than
RDF Value objects.
|
com.bigdata.rdf.store |
This package provides several realizations of an RDF database using the bigdata
architecture, including one suitable for temporary data, one suitable for local
processing (single host), and one designed for scale-out on commodity hardware.
|
com.bigdata.relation |
This package includes an abstraction layer for relations.
|
com.bigdata.relation.locator |
Abstraction layer for identifying relations and relation containers in much
the same manner that indices are identified (unique name and timestamp).
|
com.bigdata.search |
This package provides full text indexing and search.
