Updated by dalley over 3 years ago

In libmodulemd, it is planned to introduce an extension to version 2 of modulemd documents which differ slightly from the current v2.    A new, optional field is added, called "static_context", described thusly: 

 ~~~ 
     # context: 
     # Module context flag 
     # The context flag serves to distinguish module builds with the 
     # same name, stream and version and plays an important role in 
     # automatic module stream name expansion. 
     # 
     # If 'static_context' is unset or equal to FALSE: 
     #     Filled in by the buildsystem.    A short hash of the module's name, 
     #     stream, version and its expanded runtime dependencies. The exact 
     #     mechanism for generating the hash is unspecified. 
     # 
     #     Type: AUTOMATIC 
     # 
     #     Mandatory for module metadata in a yum/dnf repository. 
     # 
     # If 'static_context' is set to True: 
     #     The context flag is a string of up to thirteen [a-zA-Z0-9_] characters 
     #     representing a build and runtime configuration for this stream. This 
     #     string is arbitrary but must be unique in this module stream. 
     # 
     #     Type: MANDATORY 
     static_context: false 
     context: c0ffee43

 We need to add the model fields/migration and code necessary to support reading and writing this metadata, suf
