/**
 * OSTREE_REPO_METADATA_REF:
 *
 * The name of a ref which is used to store metadata for the entire repository,
 * such as its expected update time (`ostree.summary.expires`), name, or new
 * GPG keys. Metadata is stored on contentless commits in the ref, and hence is
 * signed with the commits.
 *
 * This supersedes the additional metadata dictionary in the `summary` file
 * (see ostree_repo_regenerate_summary()), as the use of a ref means that the
 * metadata for multiple upstream repositories can be included in a single mirror
 * repository, disambiguating the refs using collection IDs. In order to support
 * peer to peer redistribution of repository metadata, repositories must set a
 * collection ID (ostree_repo_set_collection_id()).
 *
 * Users of OSTree may place arbitrary metadata in commits on this ref, but the
 * keys must be namespaced by product or developer. For example,
 * `exampleos.end-of-life`. The `ostree.` prefix is reserved.
 *
 * Since: 2018.6

#define OSTREE_REPO_METADATA_REF "ostree-metadata"

/**
 * OSTREE_META_KEY_DEPLOY_COLLECTION_ID:
 *
 * GVariant type `s`. This key can be used in the repo metadata which is stored
 * in OSTREE_REPO_METADATA_REF as well as in the summary. The semantics of this
 * are that the remote repository wants clients to update their remote config
 * to add this collection ID (clients can't do P2P operations involving a
 * remote without a collection ID configured on it, even if one is configured
 * on the server side). Clients must never change or remove a collection ID
 * already set in their remote config.
 *
 * Currently, OSTree does not implement changing a remote config based on this
 * key, but it may do so in a later release, and until then clients such as
 * Flatpak may implement it.
 *
 * This is a replacement for the similar metadata key implemented by flatpak,
 * `xa.collection-id`, which is now deprecated as clients which supported it had
 * bugs with their P2P implementations.
 *
 * Since: 2018.9
