“Semantic Maps is an extension to Semantic MediaWiki (SMW) that adds semantic capabilities to the Maps extension and adds the datatype Geographic coordinate. This includes the ability to add, edit, aggregate and visualize coordinate data stored through the Semantic MediaWiki extension. It is based on the Maps extension and replaces the earlier implementations Semantic Google Maps and Semantic Layers.” Semantic Maps, retrieved Aug 2013

Download, versions and dependencies

Semantic maps is based on other extensions. Typically, you must include Validator (or ParamProcessor), SMW, semantic Forms, Maps, and finally Semantic Maps.

As of August 2013, you have to make a choice between and older and a newer version. In addition, documentation for ParamProcessor isn't up-to-date, i.e. some confusion of what you need. Also read Wikidata/Notes/SMW and Wikidata

Version 3.0.x

Currently (Aug 2013), alpha but should be working fine if you also upgrade all the dependencies. Same setup as 2.0.x.

• Copy/paste [Semantic_MediaWiki#Git_copy.2Fpaste_list this list GIT list] (from the Semantic MediaWiki article.

Version 2.0.x

Download and instructions: Extension:Semantic_Maps

• Maps 2.0.1 or above
• ParamProcessor 1.0 or above. This is a new version of Validator and it also keeps the validator extension directory.
• DataValues (needed by ParamProcessor)
• Mediawiki 1.18 or above
• PHP 5.3 or above

Version 1.0.5

Download and instructions: Extension:Semantic_Maps and the old documentation wiki

• Maps 1.0.5
• MediaWiki 1.17 or above
• Validator later than 0.4.12

Installation notes

Not stable, I just write down the steps I am currently playing with - 17:35, 16 August 2013 (CEST)

• There is a severe problem with Validator and SMW (relatated to the version of this wiki).

Class '\\ValueValidators\\RangeValidator' not found in /export/data/portails/mediawiki/extensions/Validator/includes/ParamProcessor/ParamDefinitionFactory.php on line 181, referer: http://edutechwiki.unige.ch/en/Semantic_Forms

• On a test wiki (i.e. our Intranet wiki) which runs on alpha 1.22x, the extensions do seem to work...

Environment / SMW already installed

• Mediawiki version: Special:Version (this wiki)
• SMW and SMF installed and working

Read the Semantic MediaWiki article for some installation notes ...

Download

Keep a copy of directories that you will have to overwrite. Since Semantic Maps is under aggressive development, their latest versions only seem to work with the latest versions of SMW, SMF, etc. In other words, you are likely to break your wiki and therefore should be prepared to reinstall older versions ...

cd extensions
cp -rp Validator Validator.save
cp -rp SemanticForms SemanticForms.save
cp -rp SemanticMediaWiki SemanticMediaWiki.save

Then install the latest versions....

git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/DataValues.git
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/Validator.git
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/SemanticMediaWiki.git
git clone https://git.wikimedia.org/git/mediawiki/extensions/SemanticForms.git
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/Maps.git
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/SemanticMaps.git

Configure LocalSettings.php

(1) Add DataValues before Validator

(2) Add the SemanticMaps after all the other SMW extensions (e.g. Validator, SMW and SMF and Maps).

Example configuration:

// Start of SMW namespaces (after 106/107 = Coap)
$smwgNamespaceIndex = 108;
# DataValues (needed for ParaProcessor)
require_once( "$IP/extensions/DataValues/DataValues.php" );
# aka ParamProcessor (needed for SMW)
require_once( "$IP/extensions/Validator/Validator.php" );
# SMW
include_once("$IP/extensions/SemanticMediaWiki/SemanticMediaWiki.php");
enableSemantics('edutechwiki.unige.ch'); // adjust to yours

$smwgShowFactbox = SMW_FACTBOX_NONEMPTY;
// $smwgShowFactbox = SMW_FACTBOX_HIDDEN;

include_once("$IP/extensions/SemanticForms/SemanticForms.php");

# If one or more of your fields can contain internal links entered by users (e.g., "This is a [[cat]]")
$smwgLinksInValues = true;

# Semantic Drilldown. Needs yet another namespace
$sdgNamespaceIndex = 118;
include_once("$IP/extensions/SemanticDrilldown/SemanticDrilldown.php");

# Semantic Result Forms
require_once("$IP/extensions/SemanticResultFormats/SemanticResultFormats.php");

# Semantic Forms Inpus
require_once("$IP/extensions/SemanticFormsInputs/SemanticFormsInputs.php");

# Maps
require_once( "$IP/extensions/Maps/Maps.php" );
# Semantic Maps
require_once( "$IP/extensions/SemanticMaps/SemanticMaps.php" );

Understanding and Testing Maps

Since SemanticMaps are based on Maps, it's a good idea to understand how to use Maps first.

Read:

• coordinates
• geocoding
• Maps/Displaying maps

Try a simple Geocoding function like this:

{{#display_map:address=40 bouledvard du Pont-d'Arve, Geneva, Switzerland}}

It should produce something like that, i.e. the location where this very page has been written :)

Loading map...

• Insert stuff and export the wiki code, then paste into some page.
