On the activities view we should have an optional column for assay_parameters and activity_properties. These are already included in the assay and activity web services.

For the moment, these should be concatenated for each activity_id (see e.g., DrugMatrix data on old interface: https://www.ebi.ac.uk/chembl/old/assay/inspect/CHEMBL3885882 -> view activities. Though ignore column headers - what's shown is activity_properties!)

This is still not in elasticsearch, https://github.com/chembl/GLaDOS-es/issues/31 needs to be done first.

The data is ready, both activity properties and assay parameters have been added: Assay params example: https://www.ebi.ac.uk/chembl/glados-es/chembl_26_activity/_search?q=exists:_metadata.assay_data.assay_parameters

activity props example: https://www.ebi.ac.uk/chembl/glados-es/chembl_26_activity/_search?q=exists:activity_properties
