This Agora is a wiki like experimental social network and distributed knowledge graph. A node is the set of all notes and resources with a given title or otherwise mapping to an entity description. Subnodes (blocks) in a node can come from a variety of sources; they are resources volunteered by Agora users through their independent repositories. As of August 2021, these are mostly notes from digital gardens. The wikilink is the heart of this Agora: wikilinks serve as a tool to indicate a social context assembled out of individual and group contributions. In this Agora, foo bar will resolve to every resource that identifies with entity 'foo'; in particular, currently every file named foo-bar.md, foo-bar.jpg, foo-bar.png, etc. An Agora tries to best-effort integrate user contributions while preserving meaning and volunteering interesting information. You can also think of it as a sequential wiki.
An open source semantic network (Creative Commons license) for AI and ML development. Semantic nets encode the meaning of words and concepts for information processing systems. Seems to encompass several spoken languages. Curated to avoid stereotypes. Still an active project. Data elements have a concept of external URLs, which link to other data sources with machine-parseable data related to that element.

The homepage of the Open Graph protocol, a system of tags for turning web pages into smart objects in a social graph.
