Compatible with Fedora Version 3.0-3.3. |
1. Overview
This service is part of the Fedora Service Framework. It constructs Fedora objects from uploaded Submission Information Packages ("SIPs") and ingests those objects into a Fedora repository. It is exposed as a REST-style web service that accepts input via HTTP POST and (if successful) returns an XML document with the list of PIDs of the ingested objects.

#
# Required settings for remote Fedora repository.
# These are used for the pid generation and ingest functions.
#
fedora.baseURL = http://localhost:8080/fedora/
fedora.user = fedoraAdmin
fedora.pass = fedoraAdmin
#
# Optional preferred namespace part for PIDs.
# Comment this out to use the default from the target Fedora repository
#
pid.namespace = demo
|
...
Once installed, the service will be exposed from your servlet container at "diringest/ingestSIP". For example:
| Panel |
|---|
http://localhost/diringest/ingestSIP |
...
Navigating the URL above using your browser will present a simple HTML form where you can upload a SIP file, an optional rules file (if you want to use non-default conversion rules). Select "Submit". A successful submission will result in an XML file that contains a list of the PIDs of the objects that were ingested.
...
A successful response will return a 200 (OK) HTTP status code and a simple XML file containing PIDs, such as the one below:
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
<?xml version="1.0" encoding="UTF-8"?> |
...
<pidList> |
...
<pid>demo:42</pid> |
...
<pid>demo:43</pid> |
...
<pid>demo:44</pid> |
...
<pid>demo:45</pid> |
...
</pidList> |
4. Using the SIP2FOX Utility
The "SIP2FOX" utility is useful for command-line testing of SIPs and conversion rules. It is included in the distribution's "sip2fox" directory. To invoke it, change to that directory and type:
| Panel |
|---|
sip2fox sipFile.zip outputDir [fedoraHost fedoraPort fedoraUser fedoraPass [pidNamespace]] |
If you only specify a SIP file and an output directory, the program will use a test PID generator for creating the objects. If you specify Fedora Repository login information, that repository's PID generator will be used instead. To use a PID namespace other than the default for a repository, specify it as the last parameter.
The SIP2FOX utility uses the rules that reside in the config/crules.xml when it runs.
5. Preparing a SIP
| Anchor | ||||
|---|---|---|---|---|
|
A SIP file is a ZIP file containing metadata and content for a set of to-be-created Fedora objects.
...
Sample SIP files and a readme.txt file with descriptions of each are included in the sip2fox/samples directory in the diringest distribution.
6. Specifying Conversion Rules
| Anchor | ||||
|---|---|---|---|---|
|
A conversion rules file is used by the service (or sip2fox) in deriving RELS-EXT relationships from the hierarchical structure (the structMap) in the SIP.
The XML schema for conversion rules is included in the diringest distribution's sip2fox/config/ directory. There you can also find the default crules.xml file, which illustrates the use of several templates. Copyright © 2006-2007 Fedora Project, 2008 Fedora Commons, Inc.
