The following is a list of basic concepts that you need to understand how Solid works. You can also check out the following presentation that introduces some of them: RDF in SOLID.
To learn more about Solid in general, visit https://solidproject.org.
- Solid POD: This is your personal storage where Solid applications store files.
- Identity provider: This is the service used to perform authentication, it is often served in the same url as your POD (but not always).
- WebId: The url that identifies you as a person, for example
https://noeldemartin.solidcommunity.net/profile/card#me. WebIds can also identify organizations and other entities, it's not limited to individuals. - Solid document: The data stored in your POD can either be a binary, like an image or video, or a document with semantic information (an RDF document). Although these are called documents, this doesn't mean that they are stored in a text file. Documents are represented by a url, and a Solid POD can persist them in any way (text files, database, etc.). As a developer, you don't care about the persistance format because you interact with those using the Solid protocol.
- Solid container: A collection of documents and binary resources. Learn more.
- Solid Profile: This is the document that contains information about you. It is the document that contains your webId. For example
https://noeldemartin.solidcommunity.net/profile/card. - RDF: Resource Definition Framework, the abstract data representation language for data in Solid. Learn more.
- Turtle: A specific RDF encoding format. Learn more.
- SPARQL: Query language used to query RDF data. Learn more.
