+**DSSE Type Data Documentation**
+
+This document provides a definition for each field that is not otherwise described in the [dsse
+schema](https://github.com/sigstore/rekor/blob/main/pkg/types/dsse/v0.0.1/dsse_v0_0_1_schema.json). This
+document also notes any additional information about the values
+associated with each field such as the format in which the data is
+stored and any necessary transformations.
+
+**How do you identify an object as an DSSE object?**
+
+The "Body" field will include an "dsseObj" field.
+
+**Recognized content types**
+
+- [in-toto
+  statements](https://github.com/in-toto/attestation/tree/main/spec#statement)
+  are recognized and parsed. The found subject hashes are indexed so
+  they can be searched for.
+
+**What data about the envelope is stored in Rekor**
+
+Only the hash of the payload (the content covered by the digital signature inside the envelope), the hash of the entire DSSE envelope (including signatures),
+the signature(s) and their corresponding verifying materials (e.g. public key(s) or certificates) are stored.
+
+Even if Rekor is configured to use attestation storage, the entire DSSE envelope will not be stored.
