turn tests into web services

[menzowindhouwer]

https://github.com/CLARIAH/pyFAT/blob/develop/src/pyfat/resources/metrics/clarin_fip_metrics_v0.3.yaml defines a number of tests each identified by a metric_test_identifier, all these tests should become little web services:

1. make for each test a small yml file, e.g.CLFIP-F1-01M-1.yml

metric_test_identifier: CLFIP-F1-01M-1 metric_test_name: "Check to see if the selflink is a handle" metric_test_score: 0.5 metric_test_requirements:

• test: "xpath:starts-with(//cmd:MdSelfLink, 'hdl:')" modality: all

  
  2. a flask server that creates an endpoint for each yml file, e.g. http://localhost/test/CLFIP-F1-01M-1
  1. it takes a POST of a CMDI record
  2. runs the test (see how https://github.com/CLARIAH/pyFAT/blob/develop/src/pyfat/__main__.py#L97 runs the test)
  3. return the result as JSON

https://github.com/CLARIAH/pyFAT/blob/develop/src/pyfat/resources/metrics/clarin_fip_metrics_v0.3.yaml#L171 needs an FACETS environment variable that points to a JSON dump of the facets in the VLO. We need to solve this differently ... skip for now. Same is true for https://github.com/CLARIAH/pyFAT/blob/develop/src/pyfat/resources/metrics/clarin_fip_metrics_v0.3.yaml#L178
