data pod

A data pod is a place for storing documents, with mechanisms for controlling who can access what.

Solid app

A Solid app is an application that reads or writes data from one or more storages.

URI

A Uniform Resource Identifier (URI) provides the means for identifying resources [RFC3986].

resource

A resource is the target of an HTTP request identified by a URI [RFC7231].

container resource

A container resource is a hierarchical collection of resources that contains other resources, including containers.

root container

A root container is a container resource that is at the highest level of the collection hierarchy.

resource metadata

Resource metadata encompasses data about resources described by means of RDF statements [RDF11-CONCEPTS].

agent

An agent is a person, social entity, or software identified by a URI; e.g., a WebID denotes an agent [WEBID].

owner

An owner is a person or a social entity that is considered to have the rights and responsibilities of a data storage. An owner is identified by a URI, and implicitly has control over all data in a storage. An owner is first set at storage provisioning time and can be changed.

origin

An origin indicates where an HTTP request originates from [RFC6454].

read operation

A read operation entails that information about a resource’s existence or its description can be known. [Source]

write operation

resource

A resource is the target of an HTTP request identified by a URI [RFC7231].

container resource

A container resource is a hierarchical collection of resources that contains other resources, including containers.

root container

A root container is a container resource that is at the highest level of the collection hierarchy.

ACL resource

An ACL resource is represented by an RDF document [RDF11-CONCEPTS] that includes Authorizations determining access to resources.

Authorization

An Authorization is an abstract thing which is identified by a URI and whose properties are defined in an ACL resource, e.g., access modes granted to agents the ability to perform operations on resources.

access mode

An access mode is a class of operations that can be performed on one or more resources.

agent

An agent is a person, social entity or software identified by a URI, e.g., a WebID denotes an agent [WEBID].

agent group

An agent group is a group of persons or entities identified by a URI.

agent class

An agent class is a class of persons or entities identified by a URI.

origin

An origin indicates where an HTTP request originates from [RFC6454].

Notification Subscription API

An HTTP URI at which a client can initiate a subscription to notification events for a particular set of resources [RFC7231].

Notification Subscription Metadata Resource

An RDF document [RDF11-CONCEPTS] that includes metadata about the capabilities of a Notification Subscription API.

@context

The @context property is MUST be an array containing the value https://www.w3.org/ns/solid/notification/v1. Other values MAY also be present.

expiration

An ISO 8601 datetime value indicating a proposed expiration point for a subscription. A server may choose another value.

state

An opaque value representing the last known state of a resource. If the resource state is known to have changed when the client establishes a subscription, an initial notification must be sent to the client. This value should correspond to a resource's ETag header value.

rate

An ISO 8601 duration value indicating the minimum amount of time to elapse between notifications sent to the client

accept

A MIME-Type value that indicates the desired serialization of the notification. For instance, text/turtle may be acceptable.

source

The source property is used in the body of the subscription response. The value of this property MUST be a URI, using the wss scheme. A JavaScript client would use the entire value as input to the WebSocket constructor.
