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

ESS Architecture

ESS’ microservices architecture:

Overview of ESS front-end and back-end services.

Pod Management

Pods are where users store their data. When ESS provisions a new Pod, it creates the Pod with the URL https://<ESS domain>/<username>/. As part of the process, ESS also creates a WebID, https://<ESS domain>/<username>/profile/card#me, for the user.

When creating a Pod, ESS creates the following default structure under the Pod’s root (where the Pod is represented as a directory structure):

<Pod's root> = https://<ESS domain>/<username>/
├── 📁 policies/
├── 📁 profile/
│       └──📄 card
├── 📁 inbox/
├── 📁 private/
├── 📁 public/
└── 📁 settings/
        └── 📄publicTypeIndex.ttl
        └── 📄privateTypeIndex.ttl
        └── 📄prefs.ttl

ESS fully supports the W3C Linked Data Platform (LDP) specification. As such, navigating, creating, deleting and editing resources within a Pod is directly supported via the standard interfaces. For more information, see LDP Service.
