Create metanorma-plugin-oscal for parsing and accessing OSCAL content

[ronaldtse]

As described in lutaml/oscal#2 .

The implementation of this gem will be similar to that of metanorma-plugin-glossarist.

From these two documents we need to come up with some good "macros" such that people can use them to render OSCAL content.

@ronaldtse From what I understand we would require the following for OSCAL plugin

• If there is a key named params in oscal.yaml file then we will use that to fill the inserts directives in the yaml file as mentioned here
• Block directives something like we have in metanorma-plugin-glossarist
  • [oscal, <file name>, <context name>]
• Dataset Directives
  • :oscal-dataset: <dataset name>:<file_name>

For reading the OSCAL data from yaml files we can use https://github.com/metanorma/oscal-ruby gem.

Did I get this right or do we need to do something else?

@HassanAkbar sorry for the late reply on this one. Yes this is correct.

We should however update the oscal-ruby gem first for this issue:

• Utilize OSCAL "metaschema" for parsing OSCAL lutaml/oscal#18
