Semantic mediawiki extension

The snicdocs wiki uses the semantic mediawiki extension, which enables nifty things like dynamic generation of lists, tables and mashups based on tagged data in ordinary wiki pages. The annotation is unobtrusive, e.g:

[[competence::Python]] to make Python

and the search/generate syntax is equally straightforward

{{#ask: [[Category:Software]] [[Category:Bioinformatics]] |?centre }} to make redacted, do not use before the extension is properly installed, or it may mess up the page's categories

as long as we do not let nomenclature run rampant and diverge (see: the problem with the semantic web).

Notice

In case the examples appear in red, or if you see similar broken links with double colons in them in other places on the wiki, do not edit the links. They appear because you have happened to come across the pages before we have managed to install the semantic mediawiki extension properly on our production server. This problem should disappear very shortly, and if it persists beyond your definition of shortly, notify User:Joel Hedlund (NSC).

Recommendations for editors

Set up your watch lists and notifications

1. Go to your preferences page and add your email.
2. Configure your account so that pages you create automatically get added to your watchlist, and that notifications will go to your email.
3. Check the list of Special:UnwatchedPages. Is it zero length? Otherwise something is wrong. Is any of your pages on there? Add them to your watch list.

Set up your user page correctly

1. Tag your user page with the categories "application expert" and your research area (e.g: [[category:application expert]] [[category:computational chemistry]]).
2. List your special competences in the clear using semantic medawiki property tags, like so [[competence::python]] to make e.g: python, note double colons.
3. Tag your affiliation in the clear using a "centre" property tag, e.g: [[centre::NSC]], note spelling.

Naming scheme and protocol

Titles, headings and names

Capitalisation matters in mediawiki, to the point that you only get to have some control over it. Case in point: Category:Molecular dynamics and Category:molecular dynamics go to the same page, but Category:Molecular Dynamics does not (and don't you go create it!). Therefore:

All titles, headings and names, including category names and property names, should be in all lowercase, except the first character which should be a capital letter, like so:

Recommendations for editors
Editing policies
Application experts
Category:Research area
Property:Competence

Mediawiki automatically capitalises the first letter of all names, which has the benefit that one can readily type most markup in all lowercase, like so:

[[competence::python]], [[category:research area]], etc...

Widely accepted acronyms like SNIC, NSC or HMMER are of course exceptions from this rule, and should be in all uppercase.

Application experts

Are spelled as such, or as "application expert". All lowercase in plain text, capitalized A where style so dictates (page titles, headings, wiki links, wiki names, etc...). All other spellings are in error. If you see one, change it.

For motivation:

1. This is the way it's spelled in the original research grant application.
2. It is not analogous to systems experts, physics experts or gymnastics experts. Appliction is not a field per se. Besides: see Kung-fu expert, and she will set you straight.
3. What application experts are experts on, is applying scientific algorithms and methods within their research area on high performance computing resources. Not just on the programs ("Applications") within that area.

Why does this matter? It matters because Wiki. We need 100% consistent naming, or else content that should be sorted together will end up separated for stupid reasons, and that will make the site harder to navigate and make content harder to find, and that will just plain make things look bad.

Categories and properties

The snicdocs wiki makes extensive use of categories, in part to simplify navigation for the users, but mostly because it permits straightforward creation of dynamically generated lists, tables and mashups using the semantic mediawiki extension. This, however, requires generous peppering of category and property tags onto wiki pages, using great restraint and strict discipline so that nomenclature does not run rampant and diverge (see: the problem with the semantic web).

Categories and properties have many things in common, however categories tend to be easier to use while properties are more flexible. Categories are big things. Adding categories to a page not only annotates the page to sort under those categories, but also and adds cross links and generates indexes. They are great for searching and finding, but less good for dynamic generation of content. For example, this table:

{#ask: [Category:Bioinformatics] [Category:Application expert] | ?centre | ?competence }}

could not be generated if the pages had not been annotated with properties stating that NSC is a place where a person works, and that these other things are stuff they do good.

When to use one or the other should be quite obvious from gut feeling or looking at examples. If in doubt: use categories. If using categories leads to awkwardness or unwanted effects, use properties.

Guidelines for creating new categories and properties:

• Do not invent categories and properties recklessly! Check these lists first, to see if any of the already existing ones may suit your needs:
  • Special:Categories
  • Special:Properties
• Use singular for names. E.g. Applications expert, Resource, Centre...
• Use descriptive and unambiguous names. Especially for properties. Keep in mind that these will be used to define searches and will also end up as headings in dynamically generated tables, unless other people do extra work to change it on each use.
• Are you creating a new subcategory? Categories can be nested in a DAG (tree) structure. Look at the current list of top categories:
  • Special:UncategorizedCategories

Does yours fit on that list, or will it fit better as a sub(-sub)-category? Drill down and see, and annotate your new category accordingly.

• What does it mean, exactly? What does it entail? How should it be used? Add a brief and unambiguous description to the property page (eg: Property:Competence, or Category:Application expert). Leave no room for misinterpretation, as this could potentailly could make your work useless.
• Use Type:Page (the default) for properties. You of course have lots of freedom when it comes to selecting a type for your property (cf. Special:Types), but generally, you should use the default unless it would be ludicrous to do so (e.g. it's a number, date, etc...). These are examples where the default "Type:Page" is the most useful: python, MSA, NSC.
