# Attachment

`org.hypercerts.context.attachment`

An attachment links supporting documentation to one or more existing records. It can reference files, documents, external URIs, or IPFS content, and can attach to any record type via strong references.

Attachments are useful for providing evidence, documentation, or additional context for hypercerts. For example, you might attach a research paper to an activity claim, link a GitHub repository to a software project, or include photos documenting environmental work. Each attachment includes a title, optional description, the URI or content reference, and an array of strong references to the records it supports.

For the full schema, see [`org.hypercerts.context.attachment`](https://github.com/hypercerts-org/hypercerts-lexicon/blob/main/lexicons/org/hypercerts/context/attachment.json) in the lexicon repo.
