Web Services: MetadataService
[Applies to: Microsoft Dynamics CRM 4.0]
The metadata for your Microsoft Dynamics CRM installation is in tables in the Microsoft SQL Server database. These tables contain the entity, attribute, and relationship definitions for each organization. This includes the metadata for your customizations.
The MetadataService Web service contains the messages that you use to read or write the definitions for all the entities in a Microsoft Dynamics CRM installation. It can also be used to build a client-side cache.
The metadata service can be used to perform the following actions:
- Retrieve all the metadata to create a metadata cache in a client application.
- Determine whether the metadata has changed since a previous retrieve.
- Retrieve all the entities and determine which ones are custom entities.
- Retrieve the metadata for a specific entity, either system or custom.
- Retrieve the attributes for an entity.
- Retrieve the metadata for a specific attribute such as the possible state names or picklist values for an attribute.
- Create a custom entity.
- Add or update an attribute for an entity, either system or custom.
- Create or delete a relationship between two entities.
- Add or remove an option from a picklist attribute.
- Write an installation and uninstall program for your custom solution.
