Introduction to the Platform

From n² wiki

(this is work in progress)

The data in the Platform is partitioned into multiple stores. A store consists of two “boxes” – a contentbox designed for unstructured or binary blobs and a metabox designed for holding richly structured metadata. The metadata in the metabox may be about the content in the contentbox or it may be unrelated. The metabox is implemented as an RDF triple store. As content is added to the contentbox metadata is automatically extracted from it and stored in the associated metabox. The Platform allows querying of the metabox directly using Sparql or of the contentbox using store-specific indexes. Stores can be aggregated in a number of configurations to allow querying across groups of stores.
