Map API Endpoints to CHAOSS Metrics

[sgoggins]

We have had this feature in the past. The location of the CHAOSS Metric definitions have evolved a lot, so we stopped providing this information, and related links, in our api documentation: https://oss-augur.readthedocs.io/en/master/rest-api/api.html

I suggest the best way to implement this feature would be to look at the chaoss_metric_status table, and simplify it to include the augur endpoint, and the URL for the CHAOSS metric definition in GitHub. They are published at https://chaoss.community/metrics as well. This may be a more stable URL set to use. We want each metric linked from the API docs to go directly to the metric, which can be accomplished using the URL above and a combination of "slashses" and #location-on-page information.
