Collections
A collection in eXist is very similar to a folder in a filesystem. It groups a number of
related XML and/or binary documents together. Each collection in eXist has a name
and is identified by a URI . A collection stores its own metadata , and also all of the
metadata of all of the documents present in that collection, as you can see in
Table 4-1 .
