Installation

Install collective.edtf_behavior by adding it to your buildout:

[buildout]

...

eggs =
    collective.edtf_behavior

and then running bin/buildout

After you activated the add-on in the Plone Add-ons section, you can Enable this behavior on any Dexterity based content type.

Querying

from plone import api

find any document which earliest date is 06.02.1920 or later.

results = api.content.find(
    portal_type='Document',
    date_earliest={
        'query': datetime.date(1920, 2, 6),
        'range': 'min',
    },
)

find any document which latest date is 11.11.1711 or earlier.

results = api.content.find(
    portal_type='Document',
    date_latest={
        'query': datetime.date(1711, 11, 11),
        'range': 'max',
    },
)

This package provides a DateRangeInRangeIndex named edtf_start_end_range.

find all documents that fall at least with one start/end date of there interval into the range:

results = api.content.find(
    portal_type='Document',
    edtf_start_end_range={
        'start': datetime.date(1711, 11, 11),
        'end':   datetime.date(1920, 2, 6),
    },
)

For more examples how to query the indexes, have a look at the tests .

Extending it

One could improve indexing by using a DateRangeIndex, like the effectiveRange index in Plone if needed.

<!-- Example of a DateRangeIndex like the effectiveRange index in Plone -->
<index name="edtf_date_range" meta_type="DateRangeIndex"
  since_field="date_earliest" until_field="date_latest" />
