Backwards compatibility

Introduction

MediaHaven is undergoing an internal restructuring head of the release of MediaHaven REST 2.0 API. A number of metadata fields will be changing in format. To maintain backwards compatibility the following services:

• MediaHaven REST API

• OAI

• Export with XML

Will output the metadata in the fixed version 20.3 Metadata Sidecar 20.3 without ever increasing in version in future releases. Newly introduced metadata fields after version 20.3 will be absent.

MediaHaven REST API 2.0

The upcoming MediaHaven REST API 2.0 instead will always output the metadata in the latest version of the Metadata Sidecar as was before the case with REST API 1.0 which is now fixed at version 20.3.

OAI / Export with metadata

OAI and Export with metadata have now two additional metadata formats

• mhs-head: metadata in the latest Metadata Sidecar

• mets-mhs-head: METS with embedded metadata in the latest Metadata Sidecar
