Notable Updates

Sep 7, 2017: New ready-made Virtual Machine available

A new virtual machine was just created, with the latest RDFIO 3.0.2, installed on MediaWiki 1.29 and Semantic MediaWiki 2.5. You can download it from figshare here. See also the relevant section in the installation instructions for how to import and use it.

Sep 4, 2017: Paper on RDFIO published

A paper on RDFIO was just published in Journal of Biomedical Semantics, titled RDFIO: extending Semantic MediaWiki for interoperable biomedical data management. It is open access, and contains a thorough overview of the motivations behind, and the technical architecture of the extension, that might be useful for anyone looking to make advanced use of it.

Aug 18, 2017: RDFIO 3.0.1 & 3.0.2

RDFIO 3.0.2 (and partially in RDFIO 3.0.1) contains a fix to set correct Content-type header for SPARQL results, so that the SPARQL endpoint can be used from external tools (verified using the SWI-Prolog SPARQL client as seen in the screenshot on the release page).

Aug 16, 2017: RDFIO 3.0.0

RDFIO 3.0.0 was just released, with improved permission settings, localisation, and RDF format support. See the release notes for more info!

Note in particular the new permission levels:

New permission levels: rdfio-admin, rdfio-import, rdfio-sparql
New user groups: rdfioadministrator, rdfiocurator (similar to the smwadministrator and smwcurator).
- rdfioadministrator gets all permissions (rdfio-admin, rdfio-import, rdfio-sparql)
- rdfiocurator gets content editing permissions (rdfio-import, rdfio-sparql)

See Podręcznik:Uprawnienia użytkowników for more info on how to set these permissions in your LocalSettings.php file!

Note that we changed the name of the config parameters once more, back to use the rdfiog prefix, for future-proof clarity and consistency (smw uses smwg etc). The changes that have happened are:

$rdfiogPropertiesToUseAsWikiTitle --> $rogTitleProperties --> $rdfiogTitleProperties
$rdfiogQueryByEquivURI            --> $rogQueryByEquivURI --> $rdfiogQueryByEquivURI
$rdfiogOutputEquivURIs            --> $rogOutputEquivURIs --> $rdfiogOutputEquivURIs
$rdfiogAllowRemoteEdit            --> $rogAllowRemoteEdit --> $rdfiogAllowRemoteEdit
$rdfiogBaseURIs                   --> $rogBaseURIs        --> $rdfiogBaseURIs

Thus, if you have set any of these parameters, you need to use the version in the rightmost column above, and update to that in your LocalSettings.php.

Aug 9, 2017: RDFIO 2.4.0 with SMW 2.5 support

With RDFIO 2.4.0, we now finally support the latest stable Semantic MediaWiki release, 2.5.

Update 8 August, 2017: RDFIO 2.3.0 with blank node support

With RDFIO 2.3.0, we now finally support blank RDF nodes in import data.

Introduction

This extension extends the RDF import and export functionality in Semantic MediaWiki by providing import of arbitrary RDF triples (not only OWL ontologies, as was the case before) and a SPARQL endpoint that allows write operations.

Technically, RDFIO implements the PHP/MySQL based triple store and accompanying SPARQL Endpoint provided by the ARC2 library.

The RDF import stores the original URI of all imported RDF entities in the Equivalent URI property, which can later be used by the SPARQL endpoint, instead of SMW's internal URIs, which thus allows to expose the imported RDF data "in its original formats", with its original URIs. This allows to use SMW as a collaborative RDF editor, in workflows together with other semantic tools, from which it is then possible to "export, collaboratively edit, and import again", to/from SMW.

This extensions was developed as part of a GSoC 2010 project, and later further extended as part of a Extension:RDFIO/Template_matching_for_RDFIO FOSS OPW 2014 project.

Instalacja

Easiest: Use the ready-made Virtual Machine

The absolute easiest way to try out RDFIO is to import the Ready-made Virtual Machine with RDFIO 3.0.2 (with MW 1.29 and SMW 2.5) into VirtualBox or VMWare, and just start browsing the local wiki installation.

Steps:

Download the .ova file from doi.org/10.6084/m9.figshare.5383966
In VirtualBox (should be similar in VMWare), select "File > Import appliance"
Click the folder icon
Locate the .ova file you downloaded
Click "Next", "Agree" to the license, and finally "Import", to start the import
Start the virtual machine
Click log in (No password required)
Click the icon on the desktop
You will now see a local wiki installation with an RDFIO enabled wiki, in a browser!
Enjoy!

Esay: Vagrant box

The absolutely simplest way, is to use the RDFIO Vagrant box, which will automatically set up MediaWiki, SemanticMediaWiki and RDFIO in a virtual machine in under 20 minutes.

Medium-Hard: Install semi-manually using composer

Dependencies

Composer
- See this page for installation instructions.
MediaWiki
- See this page for installation instructions.
Semantic MediaWiki
- See this page for installation instructions.
- To show the "Semantic factbox" on all pages, make sure to include this in your LocalSettings.php file:

$smwgShowFactbox = SMW_FACTBOX_NONEMPTY;

Installation steps

Assuming you have followed the steps above to install the dependencies for RDFIO:

Install RDFIO by executing the following commands in a terminal:

cd wiki_folder composer require rdfio/rdfio --update-no-dev

Log in to your wiki as a super user
Browse to http://[your-domain]/wiki/Special:RDFIOAdmin
Click the "Setup" button to set up ARC2 database tables.
If you already have semantic annotations in your wiki, you need to go to the article "Special:SMWAdmin" in your wiki, and click "Start updating data", and let it complete, in order for the data to be available in the SPARQL endpoint.

Optional but recommended steps

Edit the MediaWiki:Sidebar page and add the following wiki snippet, as an extra menu (I use to place it before just the "* SEARCH" line), which will give you links to the main functionality with RDFIO from the main links in the left sidebar on the wiki:
```
* Semantic Tools
** Special:RDFIOAdmin|RDFIO Admin
** Special:RDFImport|RDF Import
** Special:SPARQLEndpoint|SPARQL Endpoint
** Special:SPARQLImport|SPARQL Import
```
Create the article "MediaWiki:Smw_uri_blacklist" and make sure it is empty (you might need to add some nonsense content like {{{}}}).

Test that it works

Now, try adding some semantic data to wiki pages, and then check the database (using phpMyAdmin e.g.) to see if you get some triples in the table named arc2store_triple.
Access the SPARQL endpoint at http://[url-to-your-wiki]/Special:SPARQLEndpoint
Access the RDF Import page at http://[url-to-your-wiki]/Special:RDFImport
Access the SPARQL Import page at http://[url-to-your-wiki]/Special:SPARQLImport

Additional configuration

These are some configuration options that you might want to adjust to your specific use case. That goes into your LocalSettings.php file. Find below a template with the default options, which you can start from, add to your LocalSettings.php file and modify to your liking:

# ---------------------------------------------------------------
#  RDFIO Configuration
# ---------------------------------------------------------------
# An associative array with base uris as keys and corresponding 
# prefixes as the items. Example:
# array( 
#       "http://example.org/someOntology#" => "ont1",
#       "http://example.org/anotherOntology#" => "ont2"
#      );
# $rdfiogBaseURIs = array();
# ---------------------------------------------------------------
# Query by /Output Equivalent URIs SPARQL Endpoint 
# (overrides settings in HTML Form)
# 
# $rdfiogQueryByEquivURI = false;
# $rdfiogOutputEquivURIs = false;
#
# $rdfiogTitleProperties = array(
#  'http://semantic-mediawiki.org/swivt/1.0#page',
#  'http://www.w3.org/2000/01/rdf-schema#label',
#  'http://purl.org/dc/elements/1.1/title',
#  'http://www.w3.org/2004/02/skos/core#preferredLabel',
#  'http://xmlns.com/foaf/0.1/name',
#  'http://www.nmrshiftdb.org/onto#spectrumId'
# );
# ---------------------------------------------------------------
# Allow edit operations via SPARQL from remote services
#
# $rdfiogAllowRemoteEdit = false;
# ---------------------------------------------------------------

Alternative triple store connectors / SPARQL Endpoints

One of the features of RDFIO is to connect Semantic MediaWiki with a triple store, and to provide a SPARQL Endpoint. There are (already) a few extensions that offer this feature. See this page for an overview of triple store connector features. (The idea behind RDFIO is mainly focusing on the RDF import functionality, and merge of some or all of the extensions is being discussed).
