CLI: update

Use legra graph update to change data with SPARQL Update. You need write access to the selected workspace and branch.

legra graph update <statement-or-file>

Insert a fact into a named graph:

legra graph update 'INSERT DATA { GRAPH <https://example.org/people> { <https://example.org/alice> <https://example.org/name> "Alice" . } }' --branch experiment

Delete that exact fact:

legra graph update 'DELETE DATA { GRAPH <https://example.org/people> { <https://example.org/alice> <https://example.org/name> "Alice" . } }' --branch experiment

For a longer update, save the statement to a file:

legra graph update changes.ru --workspace research --branch experiment

Use a branch to review changes before applying them to shared data. Check syntax with Validate.
