The Model Manager is available to users in the SkyVault_MODEL_ADMINISTRATORS permission group. To create or edit a model you must be a member of this group. By default, the System Administrator is a member of the SkyVault_MODEL_ADMINISTRATORS group and can create models.
What is a model?
- It describes the data being stored in SkyVault.
- It allows the management of content metadata by applying custom types or aspects to the content and folders.
- It is uniquely identified by its defined Namespace, Prefix, and Name.
- It is defined using a small set of building blocks: custom types, aspects, properties, and constraints.
Custom types
A custom type enumerates the properties and relationships that a file of that type can support. Typically, types represents nodes in SkyVault with support for properties and the ability to inherit the definition of a parent type. Content and Folder are the two important types defined out-of-the-box.
Aspects
An aspect is a collection of properties that can encapsulate both data and behaviour, providing a flexible tool for modeling content. Aspects add extra functionality and properties to the models by attaching them to custom types. A file in SkyVault must be of a single type, but may have one or more aspects attached to it. By default, the content repository comprises of some out-of-the-box aspects, such as Classifiable, Versionable, and so on. To know more about aspects, see About aspects.
Properties
Properties are metadata which describes the content. For example, Author is a property which specifies the person who wrote the content.
Constraints
Constraints control the input property values. For example, you can specify that the author name must not be more than 40 characters.
