# Document Fields

The connector adds the following fields to each document that it ingests:

Field Name | Description
--- | ---
`AUTN_IDENTIFIER` | An identifier that allows a connector to extract the document from the repository again, for example during the collect or view actions.
`AUTN_MODIFICATIONS` | Provides information about how many times an item has been modified. For example:
    <AUTN_MODIFICATIONS modified="3" modified_history="FO9"/>
This field is not supported by all connectors, so it might not be present, and might not include all of the attributes described below: `modified` - the number of modifications that have been observed by the connector. This might be a minimum number; if an item is modified more than once between synchronize cycles the connector might only observe a single change (this depends on the information available from the repository). `modified_history` - the time intervals between recent modifications (up to 50, one character per interval, with the most recent change at the end of the list). To convert a character into a time duration: Convert the character to an integer, `n`, (0 to 61) by the position in this string: `0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz`. Calculate using floating point arithmetic (13/9)n. Read the resulting number as a number of seconds giving the minimum duration. Due to rounding the actual value will be in the range (13/9)n to (13/9)(n+1). For example, to read "F": `n=15`, because "F" is the 16th character in the string above. (13/9)15 = (1.44444...)15 = 248.6...This gives a minimum duration of 0:04:08. The full range would be 248.6 to 359.1 seconds, or a duration between 0:04:08 and 0:05:59. `attributesmodified` - the number of times the attributes of a file have been modified. This might be a minimum number; if an item is modified more than once between synchronize cycles the connector might only observe a single change (this depends on the information available from the repository). `attributesmodified_history` - the time intervals between attributes being modified. This field has the same format as `modified_history`.
`DocTrackingId` | An identifier used for document tracking functionality.
`DREREFERENCE` | A reference for the document. This is the standard reference field, which is used for deduplication.
`source_connector_run_id` | (Added only when `IngestSourceConnectorFields=TRUE`). The asynchronous action token of the `fetch` action that ingested the document.
`source_connector_server_id` | (Added only when `IngestSourceConnectorFields=TRUE`). A token that identifies the instance of the connector that retrieved the document (different installations of the same connector populate this field with different IDs). You can retrieve the UID of a connector through `action=GetVersion`.
