DCATR.SystemGraph (DCAT-R.ex v0.1.0)

Copy Markdown View Source

Base class for DCATR.Graphs containing application-specific operational data.

System graphs store infrastructure that supports service operations but is opaque to DCAT-R itself. Examples include version history, provenance records, inference results, shared indexes, caches, and logs.

System graphs can be deployed in two modes:

  • Distributed (in DCATR.Repository): Replicated with the repository (e.g., history graphs, provenance, shared indexes)
  • Local (in DCATR.ServiceData): Instance-specific and never distributed (e.g., caches, logs, local indexes)
