View Materialization

Dydra extends the W3C SPARQL HTTP Protocol to permit to include access to repositories which constitute materialized views. The facility permits to materialize the results for any query defined in a repository’s web interface under

http://dydra.com/<account-name>/<repository-name>/@query

An materialized request is a GET request to the repository which stores the materialized cache.

GET

A GET request to the view endpoint executes the view query against the materialized form and returns the results as the response.

http://dydra.com/<account-name>/<source-repository-name>__<view-name>__view/sparql

The accept type should correspond to the form of the source query, which may be either a SELECT or and CONSTRUCT.
