Run external tools on captured items and integrate the output

[gregjan]

Eclipse external tools feature currently works on any files that are local resources within the project. This is done via the resources API and using $selected_resource_path as a command parameter.

This feature would make another variable available for the configuration of external tool runs, something like $selected_arrangement_item_path. A variable like that would allow external tools to run on individually selected items in the arrangement.

By assigning a name to each tool, a standard Eclipse external tool run configuration can map place resulting files in standard locations, like this:

$ file -i ${CAPTURED_ITEM_LOCATION} -o ${PROJECT_LOCATION}//${CAPTURED_ITEM_ID}.xml

This would allow an Eclipse build to detect new output files and link them into a mdSec in METS, then from there back to the item in the structMap for the project.

The METS builder would need the following:

• tool name (used for output dir name and GROUPID in mdSec)
• type of mdSec to create (techMD, rightsMD, sourceMD, digiprovMD, dmdSec)
• MDTYPE, OTHERMDTYPE, MDTYPEVERSION
• MIMETYPE
• LABEL

The METS builder enables quick views of the output of external tools. The mdRefs could be pulled into the standard properties viewer, for example.
