Managing the content of the hierarchy

Registry Administrators can add and/or remove Geo-Object Types or groups to the hierarchies for the organization they are a part of.

Geo-Object Types or groups from organizations you are not a member of can also be added to a hierarchy from your organization.

Adding Geo-Object Types to a hierarchy

  1. Navigate to the Geo-Objects and Hierarchies page from the sidebar and select Hierarchies at the top of the list.

  2. Click the three-dot menu next to the hierarchy and select Edit.

    IMPORTANT: Changes to the hierarchy structure are saved immediately. While the hierarchy is open for editing, the sidebar lists the Geo-Object Types you can add. When you're done, click Close to end the edit session and restore the sidebar.

  3. Click the Hierarchy tab.

  4. Drag a Geo-Object Type from the sidebar into the hierarchy area. In an empty hierarchy, drop it on Drag Geo-Object Type to Hierarchy. It becomes the top (root) of the hierarchy.

  5. To add more Geo-Object Types, drag one onto a Geo-Object Type that's already in the hierarchy, and drop it on one of the areas that appear:

    • Add Child adds it below.

    • Add Parent adds it above. This is only offered on the root.

    • Intersect Child inserts it between the Geo-Object Type and its children.

    • Intersect Parent inserts it between the Geo-Object Type and its parent.

  6. When you're done, click Close.

Rules for building a hierarchy:

  1. A Geo-Object Type can only appear once in a hierarchy. A group and a Geo-Object Type in that group can't both be in the same hierarchy.

  2. A group can only be a child. Nothing can be added below a group.

  3. A public Geo-Object Type can't be a child of a private one.

  4. A Geo-Object Type can have more than one child.

Removing a Geo-Object Type from a hierarchy

When you remove a Geo-Object Type, its children move up to its parent. The links between its Geo-Objects and their parents in this hierarchy are deleted, and lists that use the hierarchy are marked as invalid.

  1. Open the hierarchy for editing and click the Hierarchy tab, as in steps 1 to 3 above.

  2. Click the gear icon on the Geo-Object Type you want to remove.

  3. Under Actions, click Remove from hierarchy.

  4. A message asks you to confirm that you want to remove the Geo-Object Type from the current hierarchy. Click Submit.

A Geo-Object Type can't be removed if another hierarchy inherits it (see below).

Related hierarchies and inheritance

The gear icon on each Geo-Object Type also shows its Related Hierarchies: the other hierarchies that contain it. Click one to show it next to the hierarchy you're viewing, and click Hide related hierarchy to hide it again.

A hierarchy can continue from another one by inheriting it. For example, a health facility hierarchy whose root is District can inherit the administrative hierarchy above District, such as Province and Country.

  • To inherit a hierarchy, show a related hierarchy in which your root Geo-Object Type has a parent. Then click the gear icon on your root and select Inherit. The inherited Geo-Object Types are labelled (Inherited).

  • To stop inheriting, click the gear icon on the Geo-Object Type below the inherited ones and select Uninherit.

Only the root of a hierarchy can inherit, and a hierarchy can inherit only one other hierarchy.
