Glare (from GLare Artifact REpository) is a service that
provides access to a unified catalog of structured
meta-information as well as related binary data
(these structures are also called 'artifacts').
Glare offers its users a number of important features, like:
* Custom assets — it's not just images anymore, but also Heat
templates, Murano packages, Mistral workbooks, Tacker
blueprints and so on.
* Artifacts versioning — each artifact can be supplemented
with the version in SemVer format.
* Support of multiple binary objects per artifact. From
Glare’s part, it allows to specify a set of such attributes.
* Structured properties — artifacts may contain structured
properties like ‘dict’ and ‘list’.
* Dependencies between artifacts — one artifact may depend on
the other.
* Additional filtering for artifacts with various operators.
* Importing/exporting of artifacts between clouds.
