Date types

The templates for rendering website pages (via genpages and servepages) need to accommodate various date types in "dates" fields.

single

    "dates": [
        {
          "date_type": "single",
          "label": "creation",
          "expression": "1757-01-01",
          "lock_version": 0,
          "jsonmodel_type": "date",
          "created_by": "admin",
          "last_modified_by": "admin",
          "user_mtime": "2015-10-19T22:45:20Z",
          "system_mtime": "2015-10-19T22:45:20Z",
          "create_time": "2015-10-19T22:45:20Z"
        }
    ]

inclusive

    "dates": [
        {
          "date_type": "inclusive",
          "label": "creation",
          "expression": "Date Created",
          "begin": "1804-01-01",
          "end": "1804-12-31",
          "lock_version": 0,
          "jsonmodel_type": "date",
          "created_by": "admin",
          "last_modified_by": "admin",
          "user_mtime": "2015-10-19T22:45:20Z",
          "system_mtime": "2015-10-19T22:45:20Z",
          "create_time": "2015-10-19T22:45:20Z"
        }
    ]

bulk

    "dates": [
        {
          "date_type": "bulk",
          "label": "creation",
          "certainty": "approximate",
          "begin": "1940",
          "end": "1941",
          "lock_version": 0,
          "jsonmodel_type": "date",
          "created_by": "mariella",
          "last_modified_by": "mariella",
          "user_mtime": "2016-03-02T23:57:58Z",
          "system_mtime": "2016-03-02T23:57:58Z",
          "create_time": "2016-03-02T23:57:58Z"
        }
    ]

Finding records with date types

If you have jq and installed then it is easy to scan the dataset directory for examples in your accessions.

Finding all single dates entries

    find dataset/repositories/2/accessions -type f |\
    while read ITEM; do
        jq '{"accession_id": .id, "dates":.dates}| select(.dates[].date_type == "single")' "$ITEM";
    done

Finding all inclusive dates entries

    find dataset/repositories/2/accessions -type f |\
    while read ITEM; do
        jq '{"accession_id": .id, "dates":.dates}| select(.dates[].date_type == "inclusive")' "$ITEM";
    done

Finding all bulk dates entries

    find dataset/repositories/2/accessions -type f |\
    while read ITEM; do
        jq '{"accession_id": .id, "dates":.dates}| select(.dates[].date_type == "bulk")' "$ITEM";
    done
