| − | === For newbies ===
| + | |
| − | [http://semantic-mediawiki.org/wiki/Help:Introduction_to_Semantic_MediaWiki This webpage] gives a short introduction to what SMW is and why it is useful.
| + | |
| − | | + | |
| − | === About the names of semantic properties ===
| + | |
| − | When writing queries, beware! The name of a property can be DIFFERENT from the name used in the semantic part of the wiki pages describing the objects of your query. For instance, any project page includes something like
| + | |
| − | <nowiki>{{</nowiki>Project
| + | |
| − | | [...]
| + | |
| − | | restopic=SomeTopic
| + | |
| − | | [...]
| + | |
| − | <nowiki>}}</nowiki>
| + | |
| − | But if you are writing a query to select the projects with topic SomeTopic you should NOT use
| + | |
| − | <nowiki>[[</nowiki>restopic::SomeTopic<nowiki>]]</nowiki>
| + | |
| − | Instead, you have to use the name of the property corresponding to the "restopic" field in the project page. This name is "prjResTopic": therefore your query should use
| + | |
| − | <nowiki>[[</nowiki>prjResTopic::SomeTopic<nowiki>]]</nowiki>
| + | |
| − | How can you find out the right name for the properties associated to (the content of) a page? When a page includes semantic information, clicking the "''Browse properties''" link in the toolbox on the left gives you a list of all the properties defined for that page.
| + | |
| − | | + | |
| − | ''Note 1: the correspondencies between properties and field names in the semantic code of a page are set by the relevant [[Special:Forms|semantic form]]. For instance, for a project they can be seen (and altered, if you know what you're doing...) by editing the [[Form:Project]] page.''
| + | |
| − | | + | |
| − | ''Note 2: in some cases the name of a property is preceded by a prefix in the form "PREFIX:" this means that the property has been imported from an external ontology, or defined in accordance with it. Examples of such prefixes are "A:" (referring to [http://www.w3.org/2001/Annotea/ Annotea]) and "Foaf:" (referring to the [http://www.foaf-project.org/ Friend-Of-A-Friend project]). In any case, AIRWiki properties having a prefix are used exactly in the same way of the other properties.''

| − | | + | |
| − | === HOWTO add a field to the semantic description of a project ===
| + | |
| − | We will describe the operations that had to be performed to add a new field to the description of [[Category:Project | Projects]], in order to integrate the new field with the SMW framework of AIRWiki and to make it fully usable for semantic queries. Of course, the procedure can be easily generalized.
| + | |
| − | | + | |
| − | '''IMPORTANT: this kind of operations introduce structural changes in the AIRWiki. They should be performed only after consultation with [[User:AndreaBonarini | professor Bonarini]].
| + | |
| − | | + | |
| − | Let's add the field "Coordinator" to the Project category, to describe the person that is managing the project (while the "Tutor" is in charge of the students participating to it). These are the steps:
| + | |
| − | | + | |
| − | '''1.''' Creation of a new category called "Coordinator". By using the [[Special:CreateCategory]] page, this is easy, but we are asked to specify which category (if any) Coordinator should be a subcategory of. The general rule is: ''define a new category B as a subcategory of a category A which includes all the possible elements of B, but the minimum number of elements outside B. If A doesn't exist, do not define B as a subcategory.'' By applying this rule, we define "Coordinator" as a subcategory of "Person": in fact the coordinator is most certainly a person, but can be even external to Politecnico di Milano.
| + | |
| − | | + | |
| − | '''2.''' Choice of the forms which are influenced by the change. The forms are used for simplified input of data, and are the preferred method to create new pages (when a form is available for the page, of course). Available forms are listed in the [[Special:Forms]] page: in our case, the only form to be changed is [[Form:Project]].
| + | |
| − | | + | |
| − | '''3.''' Modification of the form for Project. By editing the [[Form:Project]] wiki page, we must now insert a field associated to the Coordinator category into the form. ''Beware: this is a dangerous operation, if you are not an expert of SMW syntax.'' The best option is to use copy-and-paste judiciously. By adding
| + | |
| − | | + | |
| − | ! <nowiki>[[Property:PrjCoordinator|Coordinator(s)]]:</nowiki>
| + | |
| − | (NameSurname1; NameSurname2; ...)
| + | |
| − | | {{{field|coordinator|mandatory|autocomplete on category=Coordinator|delimiter=; }}}
| + | |
| − | |-
| + | |
| − | | + | |
| − | to the form in a suitable place, we ensure that:
| + | |
| − | * a new ''field'' (called "coordinator") is added to the form: from now on, any page created or edited using this form will possess a box where the coordinator must (note the "mandatory") be specified;
| + | |
| − | * a new ''property'' (called PrjCoordinator) has been introduced ''but not yet defined''.
| + | |
| − | | + | |
| − | '''4.''' Creation of the new property PrjCoordinator associated to category Project. After its definition, the value of the property for a specific page belonging to that category will be usable to perform queries. This is done using the special page [[Special:CreateProperty]]. This creation mask asks you to specify the kind of values of the property: in our case, we choose one at random since we are going to replace the property page's wiki code immediately after.
| + | |
| − | | + | |
| − | '''5.''' Definition of the new property. This is done by editing page [[Property:PrjCoordinator]]; in this case we simply substituted the wiki code in it with the following text, adapted from [[Property:PrjTutor]]:
| + | |
| − | | + | |
| − | <nowiki>This property is used to indicate that a [[:Category:Project|Project]] is managed by one (ore more) [[:Category:Coordinator|Coodinators]].</nowiki>
| + | |
| − | <nowiki><!-- Allowed values are all [[:Category:Coordinators|coordinators]]: {{#arraymap: {{#ask: [[Category:Tutor]]|format=list|link=none|sep=;}}|;|</nowiki>
| + | |
| − | <nowiki>x|[[allows value::x]]}} --></nowiki>
| + | |
| − | | + | |
| − | '''6.''' Choice of the templates which are influenced by the change. The templates are used to display in a standardized way the data of a page. Available templates are listed in the [[Special:Templates]] page: in our case, the only form to be changed is [[Template:Project]] (it must be changed because it defines the category Project).
| + | |
| − | | + | |
| − | '''7.''' Modification of the template for Project. ''Beware: this is a dangerous operation, if you are not an expert of SMW syntax.'' The best option is to use copy-and-paste judiciously. In our case, we perform two modifications. First, alteration of the description of the template by inserting the following text:
| + | |
| − | | + | |
| − | | coordinator=Leonardo Da Vinci
| + | |
| − | | ***NOTE:*** you can specify a LIST of coordinators, separating them with a semicolon (;). Coordinators and tutors can overlap.
| + | |
| − | | + | |
| − | Then, alteration of the graphical description of the template to add a table row showing the coordinator(s). This requires adding the following text:
| + | |
| − | | + | |
| − | |-
| + | |
| − | <nowiki>{{Tablerow|Label=Coordinator|Value={{#ifeq:{{{coordinator|}}}|||{{#arraymap:{{{coordinator|}}}|; |x|[[prjCoordinator::User:x|x]] ({{#show: User:x| ?Email }})}}}}}}</nowiki>

| − | == AIRWiki special pages dedicated to semantic content ==
| + | |
| − | | + | |
| − | The [[Special:SpecialPages]] page includes many interesting tools for the management of the semantic elements of AIRWiki. Below are those which are most useful to non-expert users.
| + | |
| − | | + | |
| − | === Browsing existing elements ===
| + | |
| − | * [[Special:Categories]] list of categories
| + | |
| − | * [[Special:Properties]] list of properties
| + | |
| − | * [[Special:Templates]] list of templates (the interesting ones are those which define a category)
| + | |
| − | * [[Special:Browse]] browse the semantic content of pages
| + | |
| − | * [[Special:SearchByProperty]] search for pages having a specific value for a property
| + | |
| − | * [[Special:Ask]] use your own semantic query to search through AIRWiki
| + | |
| − | | + | |
| − | === Creating new elements ===
| + | |
| − | * [[Special:AddPage]] create a new page with (also) semantic content, using one of the available forms
