XQuery Extension Modules - eXist: A NoSQL Database and Application Development Platform - page 512

The module distinguishes between installation and deployment steps. This is because
although the installation process is standardized by the EXPath packaging specifica‐
tion, the deployment step is not. It is implementation-defined and specific to eXist-
db. Installation will register a package with the EXPath packaging system, but will not
copy anything into the database. Deployment will deploy the application into the
database as specified by repo.xml .
The packaging mechanism and this module are described in “Packaging” on page
227 . Background information is available at http://exist-db.org/exist/apps/doc/
repo.xml .
