Holochain Links

A piece of metadata connecting one address on the Distributed Hash Table to another. Each link has a tag for storing arbitrary content and is stored in the DHT at its base‘s address.

Link base¶

The address of the record data (entries or actions) on the DHT that a link links from.

Link tag¶

An arbitrary piece of data, stored with a link, that contains application-defined information. A link tag can define an ad-hoc type for the link, be used in a query filter, or store information about the link target to avoid a second DHT query to retrieve the target’s content.

Link target¶

The address of the record data on the DHT that a link links to. Link targets have no metadata pointing back to the base, and therefore have no knowledge that they’re being linked to.
