"The TAXIICollection suite contains [TAXIICollectionStore](../api/datastore/stix2.datastore.taxii.rst#stix2.datastore.taxii.TAXIICollectionStore), [TAXIICollectionSource](../api/datastore/stix2.datastore.taxii.rst#stix2.datastore.taxii.TAXIICollectionSource), and [TAXIICollectionSink](../api/datastore/stix2.datastore.taxii.rst#stix2.datastore.taxii.TAXIICollectionSink). [TAXIICollectionStore](../api/datastore/stix2.datastore.taxii.rst#stix2.datastore.taxii.TAXIICollectionStore) pushes and retrieves STIX content to local/remote TAXII Collection(s). [TAXIICollectionSource](../api/datastore/stix2.datastore.taxii.rst#stix2.datastore.taxii.TAXIICollectionSource) retrieves STIX content from local/remote TAXII Collection(s). [TAXIICollectionSink](../api/datastore/stix2.datastore.taxii.rst#stix2.datastore.taxii.TAXIICollectionSink) pushes STIX content to local/remote TAXII Collection(s). Each of the interfaces is designed to be bound to a Collection from the [taxii2client](https://github.com/oasis-open/cti-taxii-client) library (taxii2client.Collection), where all [TAXIICollection](../api/datastore/stix2.datastore.taxii.rst) API calls will be executed through that Collection instance.\n",

"\n",
|
|
"A note on TAXII2 searching/filtering of STIX content: TAXII2 server implementations natively support searching on the STIX2 object properties: id, type and version; API requests made to TAXII2 can contain filter arguments for those 3 properties. However, the [TAXIICollection](../api/datastore/stix2.datastore.taxii.rst) suite supports searching on all STIX2 common object properties (see [Filters](../api/datastore/stix2.datastore.filters.rst) documentation for full listing). This works simply by augmenting the filtering that is done remotely at the TAXII2 server instance. [TAXIICollection](../api/datastore/stix2.datastore.taxii.rst) will seperate any supplied queries into TAXII supported filters and non-supported filters. During a [TAXIICollection](../api/datastore/stix2.datastore.taxii.rst) API call, TAXII2 supported filters get inserted into the TAXII2 server request (to be evaluated at the server). The rest of the filters are kept locally and then applied to the STIX2 content that is returned from the TAXII2 server, before being returned from the [TAXIICollection](../api/datastore/stix2.datastore.taxii.rst) API call. \n",
