TinySPARQL – low-footprint RDF triple store library

The TinySPARQL library offers a complete RDF triplestore with SPARQL 1.1 interface and a minimal footprint.

It allows creating local databases in memory or the filesystem, and accessing/creating endpoints for federated queries.

TinySPARQL is the data storage backend for the Tracker Miner FS filesystem indexer.

This is free and open source software.

Features include:

  • Based on open standards. SPARQL is a W3C recommendation. So is the RDF data model and the various file formats available for import/export (Turtle, Trig, JSON-LD).
  • Small, fast, and scalable. It is also robust and fully ACID (atomicity, consistency, isolation, durability).
  • Database format and schema updates are automatically managed. The user just needs to write and update the ontology defining the structure of the contained data. Databases will be created and implicitly updated to format changes without the need to write supporting code.
  • Versatile serialization capabilities. TinySPARQL is able to export RDF data into the same formats it can import and load into databases. It is possible to perform backups, data mirroring, data synchronization…
  • A complete set of CLI tools is included. TinySPARQL databases are fully introspectable and can be opened with no additional supporting files, the command line tools can do anything the library could do, and a number of utilities is provided.
  • Distributed data is a first class citizen. SPARQL has builtin capabilities to operate in a distributed environment, which may make it desirable to manage data that is naturally open to multiple users. TinySPARQL may interoperate with other SPARQL implementations.
