A system to propagate changes between RDF Datasets

RDF Delta

RDF Delta provides a system for recording and publishing changes to RDF Datasets. It is built around idea of change logs:

• RDF Patch - a format for recording changes to an RDF Dataset
• RDF Patch Log - organise patches in to a log of changes to an RDF Dataset with HTTP access.

RDF Patch Logs can be used for:

• Replicated datasets - 2 or more copies of a single dataset for high availability of the data.
• Incremental backup of a dataset.
• Recording changes
• Generate alerts based on changes, either to the dataset as a whole or specific resources within the dataset.

RDF Delta provides a system for keeping copies of an RDF Dataset up-to-date using the RDF Patch Log as a journal of changes to be applied.
