islandora rest api

[Aaron Krebeck]

I'm doing some testing with the Islandora Rest API and in working through the great documentation (https://github.com/discoverygarden/islandora_rest) the only thing I found lacking were some actual curl examples for novice users.  I'm attaching a few below, but I also have a question.  I've authenticated, tested a few GET requests, and created a new object.  From there I can modify the DC datastream just fine.  Now I'd like to create (and modify) a RELS-EXT datastream for this object.  I'm running into trouble with that part.  Could someone send a sample curl request for posting/modifying a new RELS-EXT datastream? 

Sample commands:

## Authenticate to Rest API ##

curl --cookie-jar ./cookies.txt -X POST -H "Content-Type: multipart/form-data" -F "name=youradminuser" -F "pass=youradminpass" -F "form_id=user_login" -F "op=Log in" "http://yourislandora.site.org/user/login"

## Describe an Object ##

curl -b ./cookies.txt "http://yourislandora.site.org/islandora/rest/v1/object/enteranamespace:andnumber"

## Create A New Object ##

curl -b ./cookies.txt -H "Accept: application/json" -X POST "http://auislandora-dev.wrlc.org/islandora/rest/v1/object" -d '{"pid":"enteranamespace:andnumber","label":"Object Name","owner":"fedoraAdmin"}'

## Delete An Object ##

curl -b ./cookies.txt -H "Accept: application/json" -X DELETE "http://auislandora-dev.wrlc.org/islandora/rest/v1/object/enteranamespace:andnumber"

Hi Aaron,

Others may have differing points of view, but I'd recommend building a RELS-EXT by defiining relationships rather than ingesting a fully formed datastream.

I have done some preliminary work on a REST ingester application, https://github.com/mjordan/islandora_rest_ingester, that seemed to work as expected when I was developing it, although I haven't put it into production yet. The code that defines relationships via the REST API starts around line 145.

HTH,

Mark

Great, thanks Mark.  I'm attaching a sample curl version of what you suggested below (it worked great, BTW) and another last example for anyone who treads this way again.

## Add a Relationship (if no other relationships exist, this will create a new RELS-EXT datastream) ##

curl -v -b ./cookies.txt -X POST -H "Accept: application/json" -d '{"uri":"info:fedora/fedora-system:def/model#","predicate":"hasModel","object":"islandora:personCModel","type":"uri"}' "http://yourislandora.site.org/islandora/rest/v1/object//relationship"

## Create A New Datastream ##

curl -v -b ./cookies.txt -X POST -H "Content-Type: multipart/form-data" -F "dsid=TN" -F "controlGroup=M", -F "multipart file as request content=@/home/user/thumbnail.jpg" "http://auislandora-dev.wrlc.org/islandora/rest/v1/object/enteranamespace:andnumber/datastream"

Hi Aaron,

Great examples. I wonder if DGI would be open to pull requests that added examples to the README?
