Inrupt’s Enterprise Solid Server (ESS) is a Solid Pod Server. That is, ESS provides/hosts Solid Pods (where Pods are data storage locations) in accordance with the Solid specification.

Pod Server


Pod Management#

ESS’ Pod provisioning service creates Pods. Pods are where users store their data, both Resource Description Framework (RDF) data and non-RDF data. With ESS’ support for the Solid Protocol specification, navigating, creating, deleting and editing Solid Resources within a Pod is directly supported via the standard HTTP interfaces.

In addition, ESS provides a Query (QPF) endpoint to query RDF (Resource Description Framework) data in the Pod.

ESS’ WebID service issues and manages WebIDs. A WebID is a URI/IRI that uniquely identifies a person, company, organization, etc.

In addition, starting in ESS 2.0, Pods and WebIDs are created independently of each other, and WebID profiles are no longer hosted on the Pods. This change allows for multiple Pods per WebID, prevents users from locking themselves out of their Pods, and allows users to obtain their WebID or Pods from alternative providers.

For more information, see WebID service.

Client ID#

An application identifies itself using a client identifier (Client ID). ESS supports the following Client ID types:
