Eprint objects contain zero or more documents, which each contain zero or more files. When you update (PUT) an eprint object the contained documents will only be replaced if the Import plugin defines new documents e.g. the Atom Import plugin will never define new documents so PUTing Atom content will only update the eprint's metadata. PUTing [[API:EPrints/Plugin/Export/XML|EP3 XML]] will replace the documents if you include a &lt;documents&gt; XML element.

If you have the <em>upsert</em> privilege objects will be created on demand, otherwise attempting to PUT to a non-existant object will result in an error.

−
Since EPrints 3.4, PUT is now designed to replace all existing metadata with the metadata provided in the request, so if a field is not included in the request it will become unset in the object.  If you only want to update and/or insert particular fields you should use PATCH.

NAME

EPrints::Apache::CRUD - Create, read, update and delete via HTTP

User Comments


SYNOPSIS

 $crud = EPrints::Apache::CRUD->new(
     repository => $repo,
     request => $r,
     datasetid => "eprint",
     dataobjid => "23",
   );

User Comments


DESCRIPTION

The CRUD (Create/Read/Update/Delete) module provides the Web API for manipulating content on the server. The API is an AtomPub implementation that exposes Import and Export plugins via simple URLs and HTTP content type negotiation.

You should use the <link> entries in the repository's home page to locate the CRUD endpoint, as they may change in the future: 

 <link rel="Sword" href="https://myrepo/sword-app/servicedocument" />
 <link rel="SwordDeposit" href="https://myrepo/id/contents" />

Examples

Create a new eprint based on a single file: 

 curl -X POST \
   -i \
   -u user:password \
   -d 'Hello, World!' \
   -H 'Content-Type: text/plain' \
   https://myrepo/id/contents
 
 HTTP/1.1 201 Created
 Content-Type: application/atom+xml;charset=utf-8
 ...

Add a file to an existing eprint: 

 curl -X POST \
   -i \
   -u user:password \
   -d 'Hello, World!' \
   -H 'Content-Disposition: attachment; filename=hello.txt' \
   -H 'Content-Type: text/plain' \
   https://myrepo/id/eprint/23/contents
 
 HTTP/1.1 201 Created
 Content-Type: application/atom+xml;charset=utf-8
 ...

Get an eprint's metadata in Atom XML: 

 curl -X GET \
   -i \
   -u user:password \
   -H 'Accept: application/atom+xml' \
   https://myrepo/id/eprint/23
 
 HTTP/1.1 200 OK
 Content-Type: application/atom+xml;charset=utf-8
 ...

Get the list of contents (documents) of an eprint in Atom XML: 

 curl -X GET \
   -i \
   -u user:password \
   -H 'Accept: application/atom+xml' \
   https://myrepo/id/eprint/23/contents
 
 HTTP/1.1 200 OK
 Content-Type: application/atom+xml;charset=utf-8
 ...

You can find more examples in the tests/84_sword.t unit test.

HTTP Content Negotiation

GET/HEAD requests are processed using Export plugins. POST/PUT requests are processed using Import plugins.

The plugin used depends on the request's Accept (GET/HEAD) or Content-Type (POST/PUT) header and the type of object being acted on. For example, the following request: 

 GET /id/eprint/23 HTTP/1.1
 Accept: application/vnd.eprints.data+xml

Will search for an Export plugin that accepts objects of type dataobj/eprint and can produce output in the MIME type application/vnd.eprints.data+xml. This will most likely be the EP3 XML plugin.

In addition to the general plugin negotiation behaviour some special cases are supported to improve compatibility with Atom Pub/Web Browser clients:

User Comments


/id/eprint/...

Requesting EPrint objects as text/html will result in a 303 Redirect to the eprint object's abstract page or, if the eprint is not public, its View page.

User Comments


/id/document/.../contents

Requesting the /contents of a Document object will return the content of the document's main file.

User Comments


/id/file/...

Requesting a File object with no Accept header (or */*) will return the file's content.

User Comments


POST /id/.../contents

When creating new records via POST, content negotiation is performed against the Import plugins.

If no Import plugin supports the Content-Type header the content will be treated as application/octet-stream and stored in a new object. The resulting Atom entry will describe the new object (e.g. the eprint object in which the new document and file objects were created).

Otherwise, the result will depend on the Import plugin's output. Import plugins may produce a single object, multiple objects or an object plus content file(s).

User Comments


Content-Type header

If no Content-Type header is given the MIME type defaults to application/octet-stream for POSTs and PUTs.

User Comments


Content-Disposition header

If the Content-Disposition header is missing or does not contain a filename parameter the filename defaults to main.bin for POSTs and PUTs.

User Comments


Updating complex objects using PUT

Eprint objects contain zero or more documents, which each contain zero or more files. When you update (PUT) an eprint object the contained documents will only be replaced if the Import plugin defines new documents e.g. the Atom Import plugin will never define new documents so PUTing Atom content will only update the eprint's metadata. PUTing EP3 XML will replace the documents if you include a <documents> XML element.

PUTing to /contents will always replace all contents - PUTing to /eprint/23/contents is equivalent to DELETE /eprint/23/contents then POST /eprint/23/contents.
