Fedora 3.0 API

DOMS metadata objects will be stored in Fedora-commons 3.0.

The API is documented here, as far as it goes: http://www.fedora-commons.org/documentation/3.0/userdocs/index.html#webservices

The structures below are used by Fedora, almost no matter which lanquage you use to interact with it. We use our own shorthand to specify the types. This schema should help you translate to your language of choise

The "fedora-types:ArrayOfString" is defined thus

<complexType name="ArrayOfString">
   <sequence>
      <element name="item" minOccurs="0" maxOccurs="unbounded" type="xsd:string"/>
   </sequence>
</complexType>

The API to Fedora is directly exported as the primary API to DOMS. We have restricted a few methods, and have some conventions about certain other should be used.

API restrictions

Fedora has the concept of state for all objects. We have added additional meaning to this term, which is described in FedoraState. Basically, an object can be Active, Inactive or Deleted. If it is Active, the only allowed change is to make it Inactive. All other attempted changes will throw exceptions. If Inactive, all changes are allowed. Changing the state from anything to Active will cause the object to be validated, and if the object is not valid, the state will not be changed.

Best practice, when perfoming changes in a set of objects it to mark each of them as Inactive, before performing any changes, and perform all changes before moving any of them back to Active.

The Fedora API is described in the the pages below.
