The [DBpedia Archivo Databus agent](https://databus.dbpedia.org/ontologies) generates only basic, static documentation for the archived snapshots of the ontologies.

## Ontology Metadata

DBpedia Archivo extracts metadata from the ontology for well known properties (e.g. dct:description). This subsection shows the content of every property individually using a separate heading.

### dct:description

Currently, the Solid protocol and its specifications lack the terms to express metadata related to the entities, roles, processes or infrastructure necessary to provide transparency to its data handling practices. In particular, these specifications do not have the terms to deal with the obligations and requirements brought by regulations related to (personal) data protection and privacy. The establishment of a metadata language such as PLASMA enables this by providing consistent taxonomies to describe the entities (e.g., providers, developers), the infrastructure, legal roles, policies, notices, registries and logs necessary to understand and establish responsibilities and accountability within the Solid ecosystem.

### rdfs:comment

This is the Turtle serialisation for PLASMA.
