A '''tag''' is an informative label attached to a [[Task]]. Tags carry no effect on planning or execution; they exist for reporting, filtering and aggregation.

A task may carry several tags. Tags are typically used to record which consumers depend on a task's output.

== Attributes ==
{| class="wikitable"
! Attribute !! Description
|-
| '''Name''' || Name of the tag.
|-
| '''Description''' || Free text.
|}

== Typical use ==
The usual pattern is to tag tasks by the department or system that consumes their data. A shared task carries every tag that applies to it:

* <code>ETL_CUSTOMER</code> — tagged ''Sales'' and ''Accounting''
* <code>ETL_ORDER</code> — tagged ''Sales''
* <code>ETL_PROFITLOSS</code> — tagged ''Accounting''

Downstream tasks can then be tagged according to the actual use of the data rather than according to where it happens to be computed.

== What tags are used for ==
* '''Filtering the Monitor.''' A tag filter restricts the task list to the tasks feeding one consumer. This is the quickest way to answer whether a particular department's data is ready. See [[Monitor console]].
* '''Statistics.''' Processing statistics can be aggregated by tag.

== What tags do not do ==
Tags have '''no effect on scheduling'''. They do not create dependencies, do not influence priority and do not group tasks for the purposes of limits. Use a [[Group]] where the intention is to affect execution, and a tag where the intention is only to label.
