Welcome to the SWORD v2 PHP client library!
-------------------------------------------
Version: 0.1

The SWORDAPP v2 PHP client library is a PHP library designed to assist with
the creation of SWORD deposit tools. The client library allows PHP code to
easily make use of the two SWORD functions:

 - GETting a Service Document
 - POSTing a package or file into a repository
 - PUTting an updated file into a repository
 - DELETEing a file or item from a repository

The library was originally written by Stuart Lewis (stuart@stuartlewis.com) as
part of the JISC funded SWORD2 project. Limited support for the library is
availble via the sword-app-tech email list:

 - https://lists.sourceforge.net/lists/listinfo/sword-app-tech

The latest version of the library can be downloaded from GitHub:

 - https://github.com/stuartlewis/swordappv2-php-library/

Licence
-------
The library is licenced with the New BSD Licence. See the file LICENCE in the
distribution directory.


SWORD Compatibility
-------------------
This version of the library is compatible with SWORD version 2.0


Prerequisites
-------------
This library requires:

 - PHP version 5
    + CURL extension
    + SimpleXML extension
    + ZIP extension (for the packager only)


How to use the library
----------------------
The easiest way to understand the library is to look at the 
test/test-swordappclient.php file which exercises all the functions and
variables of the library.

The main methods to use are from swordappclient.php:

 - servicedocument($sac_url, $sac_u, $sac_p, $sac_obo)
 - deposit($sac_url, $sac_u, $sac_p, $sac_obo, $sac_fname, $sac_packaging= '', $sac_contenttype = '', $sac_inprogress = false)
 - depositMultipart($sac_url, $sac_u, $sac_p, $sac_obo, $sac_package, $sac_inprogress = false)
 - depositAtomEntry($sac_url, $sac_u, $sac_p, $sac_obo, $sac_fname, $sac_inprogress = false)
 - completeIncompleteDeposit($sac_url, $sac_u, $sac_p, $sac_obo)
 - retrieveContent($sac_url, $sac_u, $sac_p, $sac_obo, $sac_accept_packaging = "")
 - retrieveDepositReceipt($sac_url, $sac_u, $sac_p, $sac_obo, $sac_accept_packaging = "")
 - replaceFileContent($sac_url, $sac_u, $sac_p, $sac_obo, $sac_fname, $sac_packaging= '', $sac_contenttype = '', $sac_metadata_relevant = false)
 - replaceMetadata($sac_url, $sac_u, $sac_p, $sac_obo, $sac_fname, $sac_inprogress = false)
 - replaceMetadataAndFile($sac_url, $sac_u, $sac_p, $sac_obo, $sac_package, $sac_inprogress = false)
 - addExtraFileToMediaResource($sac_url, $sac_u, $sac_p, $sac_obo, $sac_fname, $sac_contenttype = '', $sac_metadata_relevant = false)
 - addExtraPackage($sac_url, $sac_u, $sac_p, $sac_obo, $sac_fname, $sac_packaging = '', $sac_contenttype, $sac_inprogress = false)
 - addExtraAtomEntry($sac_url, $sac_u, $sac_p, $sac_obo, $sac_fname, $sac_inprogress = false)
 - addExtraMultipartPackage($sac_url, $sac_u, $sac_p, $sac_obo, $sac_package, $sac_inprogress = false)
 - deleteContainer($sac_url, $sac_u, $sac_p, $sac_obo)
 - deleteResourceContent($sac_url, $sac_u, $sac_p, $sac_obo)
 - retrieveAtomStatement($sac_url, $sac_u, $sac_p, $sac_obo)
 - retrieveOAIOREStatement($sac_url, $sac_u, $sac_p, $sac_obo)

The functions return a SWORDAPPServiceDocument, a SWORDAPPEntry, a
SWORDAPPResponse or a SWORDAPPErrorDocument object as appropriate.
These classes can then be interrogated (e.g. $servicedocument->sac_workspaces).

The main function parameters are:

 - $sac_url: The URL to interact with (e.g. service document URL, deposit URL, etc)
 - $sac_u: The username
 - $sac_p: The password
 - $sac_obo: The on-behalf-of user name (optional, can be left empty)
 - $sac_fname: Filename to deposit
 - $sac_packaging: THe packaging format of the package being deposited
 - $sac_inprogress: Whether or not the deposit should be considered 'in-progress'

The SWORD v2 specification can be seen at:

 - http://swordapp.org/sword-v2/sword-v2-specifications/


Packages
--------
Deposits can be made using packages.  By default, all SWORD v2 interfaces
should accept Atom Multipart pacakges.  These can be generated using the
'package_atom_multipart.php' class.

Some repositories will accept METS+SWAP packages.  These can be generated
using the 'package_mets_swap.php' class.


Examples
--------
An example website that can also be used for testing is included in
test/website/index.php

Configure your web server to serve that directory (and child directories)
to try the application.

Example uses of the packagers, and the SWORD client can be seen in the
/test directory.
