A project to develop a server and standalone client that demonstrates the various approaches to PROV and PROV-AQ as described in the W3C Working Group specifications (https://www.w3.org/TR/prov-aq/). Provisium will demonstrate simple reference implementations of these approaches . The reference implementations will:
- serve as a working examples (with open source code) of how end-to-end provenance systems could be constructed and
- provide a basis to compare and contrast practical implementations.
As part of this work, a generic visualization service will be created following W3C web component guidelines (https://www.w3.org/wiki/WebComponents/). Web components allow web page authors to import a web visualization, including all dependencies and networking code, with a few simple import statements. This embedding works across domains as well and provides additional reuse options as the visualization service can easily be integrated inside of dataset landing and other pages.
