[ANN] Ontogen: A Version Control System for RDF Leveraging RDF-star

Dear RDF-star Community,


I am pleased to introduce Ontogen - a new version control system specifically designed for RDF that heavily utilizes RDF-star. This is the system I've mentioned at the "RDF-star and RDF 1.2" session of the W3C Breakout Day earlier this year and in RDF-UCR issue #13 (https://github.com/w3c/rdf-ucr/issues/13).


After a year of intensive development, made possible through the generous support of the NLnet Foundation, Ontogen is now available in an early version.


Ontogen showcases the power and flexibility of RDF-star, demonstrating its practical application in versioning RDF data:


1. Core utilization of RDF-star: Ontogen uses RDF-star as the foundation for its versioning model, allowing for fine-grained control over individual statements without relying on Named Graphs. It does this based on the RTC vocabulary (https://w3id.org/rtc) to create virtual, URI-identifiable sets of statements. 
2. Speech Act-based commit model: Ontogen implements a novel commit model based on speech acts. This model enables detailed tracking of data provenance and evolution.
3. Integration with PROV and DCAT: Ontogen integrates the PROV vocabulary for comprehensive provenance information and implements repositories as DCAT catalogs.


While Ontogen is still in an early stage of development and some important extensions are pending (such as full RDF dataset support and branching), I believe it already serves as a valuable example of RDF-star's potential.
