The organization metadata is the off-chain description of a SingularityNET service and is, by default, hosted on the SingularityNET IPFS cluster. In order to use a service, the client needs to know:

• The Organization metadata
• The Service metadata

There are three ways of providing this metadata to the clients and the daemons:

• as a simple JSON file
• as a IPFS hash that points to the JSON metadata
• as a name of service in the Registry - this can be resolved to an IPFS hash, pointing to the metadata, through the Registry’s OrgMetadataURI method. Please note that only the Owner of the Organization can modify the metadata

A suspicious client should also check that hash of the metadata corresponds to the IPFS hash, otherwise the client can be attacked if the IPFS client is compromised. Fortunately, the snet-cli does this by default.

This metadata file can be directly edited before publishing to IPFS, or manipulated by snet-cli through service subcommands that have the metadata-* prefix.
