Objective

Fedora has used Axis 1.3 for SOAP support for quite some time. This is an obsolete library and better alternatives (with support for MTOM and for protocols in addition to HTTP) are available. This improvement will update Fedora to use a modern Java WS framework for SOAP and move away from Axis 1.3. In addition, it would update Fedora's SOAP API to use MTOM where appropriate.

When finished, it should be possible to integrate this work into a future feature release of Fedora, without requiring a major release. That means that it should not change Fedora's SOAP interface as perceived by outside applications.

Key Decisions

So far, the following parameters/scoping decisions have been made for the work:

• Scope: SOAP API only, but consider how the library choice affects the REST API.
• Contract-first vs Code-first? Jiri's preference is contract-first. This is compatible with our desire to keep the work relegated to the SOAP side, and wire-compatible with previous versions of Fedora
