ZIP and JAR files as collections
If the collection URI identifies a ZIP or JAR file then it is processed in exactly the same way as a directory. URI query parameters can be used in the same way, and have much the same effect.
A URI is recognized as a ZIP or JAR file URI if any of the following conditions applies:
- The standard collection finder is used and either (a) the URI uses the (non-standard)
"jar" URI scheme, or (b) the collection URI ends with
- A custom collection finder is used and the method
- A regular expression is supplied as the value of the configuration property ZIP_URI_PATTERN, and the collection URI matches this regular expression.
The value of the
recurse option is ignored in this case, and
recurse=yes is assumed.
metadata=yes is available for ZIP-based collections as well as for
directory-based collections. The set of properties returned in the resulting map is slightly
different, for example it includes any
comment field associated with the ZIP file
entry. Note that no items are returned in respect of directory nodes within the ZIP file; only
leaf nodes are represented.
