lsup_repo: repository services: organizes RDF data into "resources" made up of several named graphs; framework-managed and user-defined triples; resource-centric CRUD methods; binary storage and basic preservation facilities; structures (containers/sets, linked lists, ORE proxies, etc.); versioning, event stream. Built upon lsup_rdf. Written in C. C and Python APIs; command-line utilities.

lsup_server: REST API and read-only GUI for lsup_repo: browse (click-through) and query (matching pattern) facilities. Likely written in Python. REST API.
