Create or edit a metadata hosting rule

Create metadata hosting rule for CIs to assist in correctly identifying dependent CIs during the business discovery process and service mapping. Discovery calls the identification API that applies metadata rules.

Before you begin

A hosting rule is a relationship definition between two CIs, structured as: <CI Type1> <relationship type> <CI Type2>. To create a hosting rule, you need to add a CI type as <CI Type1> in the relationship rule, and then define the second portion of the relationship rule which is the relationship type and <CI Type2>. The entire set of hosting rules is organized as groups according to the top-level hosted CIs.

A hosting rule implicitly contains two rules, which are the reversal of each other. When you create the rule '<CI Type1> <relationship type> <CI Type2>', the rule '<CI Type2> <reversed relationship type> <CI Type1>' is automatically added.
