This repo is a Vagrant environment that supports spinning up two different implementations of SWORD v2 servers:
- Simple Sword Server (SSS), the reference implementation written in Python
- swordpoc, a very minimal implemention written in Java
To use the Vagrant VM, install Vagrant from http://vagrantup.com and VirtualBox from http://virtualbox.org and run the following commands:
git clone https://github.com/dvn/swordpoc.git
git submodule init
git submodule update
vagrant up
vagrant ssh
In one of the steps below, we clone the code from https://github.com/swordapp/Simple-Sword-Server
The main point of this exercise is to deposit "example.zip" into the SWORD server using curl.
Please note that you'll need to replace the UUIDs and timestamp below based on the output you see.
vagrant up
vagrant ssh
sudo su -
git clone https://github.com/swordapp/Simple-Sword-Server.git
cd Simple-Sword-Server
python setup.py install
mkdir /tmp/sss-server
cd /tmp/sss-server
cp /root/Simple-Sword-Server/sss/sss-1.0.py sss.py
easy_install web.py
easy_install lxml==2.3.4
python sss.py &
cd /tmp/sss-client
curl -s -i -H "X-On-Behalf-Of: obo" http://sword:sword@localhost:8080/sd-uri | grep col-uri | head -1
# note UUID from output above
curl -i -H "X-On-Behalf-Of: obo" --http1.0 --data-binary "@example.zip" -H "Content-Disposition: filename=example.zip" -H "Content-Type: application/zip" sword:sword@localhost:8080/col-uri/f19ae45f-5455-4b10-96a4-25396bb8a228
cd /tmp/sss-server/store/f19ae45f-5455-4b10-96a4-25396bb8a228/6d56e25c-c837-4138-b7c7-23e6a912d3eb
unzip 2013-06-17T16\:52\:36Z_example.zip
cat example/hello.txt
In the example above, "example.zip" is deposited into a SWORD collection, but let's imagine a more complicated example.
Let's say we want to perform the following steps:
- Create a resource with an atom entry (i.e. an XML file): http://swordapp.github.io/SWORDv2-Profile/SWORDProfile.html#protocoloperations_creatingresource_entry
- Upload example.zip to the newly created resource: http://swordapp.github.io/SWORDv2-Profile/SWORDProfile.html#protocoloperations_editingcontent_binary
These steps translate into two distinct HTTP request, as explained by the SWORDv2 spec lead, Richard Jones...
It is my plan and hope to back all of the multipart OUT of the sword spec for a future version (like a 2.1), so I strongly recommend not using multipart deposit. Instead do a POST of an Atom Entry and a PUT of the Media Resource in two distinct HTTP requests.

(For brevity, we only include 2 of the 10 collections in the Service Document)

This creates a number of files under the "4e1f7a9a-f8d4-4795-b230-195acb6680c9" collection:

70566b02-76a9-496d-b1bb-356ba9acc7f2/sss_statement.xml
We can think of "70566b02-76a9-496d-b1bb-356ba9acc7f2" as the unique identifier for the resource we just created. It contains a number of files:
atom.xml
matches exactly theatom-entry-study.xml
file we used to create the resource.sss_deposit-receipt.xml
is the output we saw from the curl command when we created the resource.sss_metadata.xml
is a simpler version ofatom.xml
(i.e.<dcterms:creator>
becomes just<creator>
).sss_statement.atom.xml
shows the state of the resource, indicating the following: "The work has passed through review and is now in the archive".sss_statement.xml
is similar tosss_statement.atom.xml
in that it shows the state, but is longer and in RDF format.
Next we upload example.zip to the resource we created ("70566b02-76a9-496d-b1bb-356ba9acc7f2").
We use --upload-file for this, which does a PUT.

The atom.xml
