A RESTful API to a DA-NRW (Digitales Archiv - Nordrhein-Westfalen) instance. The API intends to conform to the OAIS workflow. It has been tested using version "Oberntudorf 0.6.5-p1" of DA-NRW.

Requirements

• node.js (http://nodejs.org/)
• DA-NRW (https://github.com/da-nrw)

Installation

$ git clone https://github.com/StephanU/danrw-rest-api.git
$ cd danrw-rest-api
$ npm install
$ cp config.json.sample config.json
$ vi config.json # set configuration parameters according to the da-nrw installation
$ node index.js

API prefix

The following prefix has to be prepended to all api urls.

/api/v1

Thus if starting the node process locally the final url would be:

http://localhost:3000/api/v1/<api path>

IDs

Some api urls need IDs to refer to packages. The follwing IDs are supported.

Name	Type	Description
identifier	string	The identifier of the ingested data generated by the DA-NRW (e.g. "1-20141028174").
urn	string	The URN of the ingested data generated by the DA-NRW (e.g. "urn:nbn:de:danrw-1-20141028174").
origName	string	Original name of the ingested file (e.g. "20141101 MyIngest.tgz").

Authentication

All api urls require http basic authentication.
