Work item tracking resources

Get, create, and update bugs, tasks, and other work items for your team. Queries allow you to use the full power of the work item query language to search for and filter work items. You can use the work item query language to get to each work item that satisfies the query. Work items retain a full history, and you can get each full revision of the work item, or just the updates that were made in each revision. Work items can also be tagged.

Work item metadata resources

Work items are governed by metadata. Some of the metadata is scoped to a specific project, and other metadata is scoped to a project collection (like your VSTS organization's default collection).

Project-scoped metadata

Your project has a set of work item types. Each work item type may belong to a category such as "requirement" or "bug" to define its role in the project. Classification nodes define the set of values that can be used in the area and iteration fields for the work items in the project.

• Categories
• Classification nodes (areas and iterations)
• Work Item Types

Collection-scoped metadata

Work item types share fields and relation types (links and attachments) with other types of work items.

• Fields
• Relation types
