Build app by running ant. Install .xar in eXist-db (version 2.2 upwards) through the Dashboard.
Call http://localhost:8080/exist/apps/merula/plays/sha-ham101.html. standoff2inline.xql then inserts the annotations stored in /db/apps/merula/data/annotations into the base text (stored as /db/apps/merula/data/sample_MTDP10363.xml), first the editorial annotations, then the feature annotations, thereby re-generating a TEI document, and displays it as html.
Run inline2standoff.xq in eXide with let $output-format := 'doc'. This takes the original (inline) TEI text sample_MTDP10363.xml stored in /db/apps/merula/mopane and generates its base text version, plus all of its inline annotations, and stores this in /db/apps/merula/data. This overwrites the sample data.
Add an editorial annotation by running add-annotation.xq in eXide and the existing feature annotations that follow it are kept in sync.
See Implementing Standoff Annotation for a discussion of the issues involved and the approaches adopted.
