Help talk:Annotation naming guideline

"[[is located in::Asia]]" and "[[is member of::European Union]]" is against current practice on Ontoworld. Uniformity is damaged if people start following this guideline. If this is made an official guideline a bot should make all necessary changes. If not, I recommend to follow the current practice.

Even apart from what the current practice is, I prefer the form "located in" and "member of", with the convention that this means "currently". If needed an additional relation such as relation:was capital of can be introduced.

Adding unnecessary words in a property name just to facilitate searching does not seem a good idea. Giving a guideline not to include "is" as first word in a search phrase seems better.--Patrick 08:21, 10 December 2006 (CET)

Well, That are good points. Now, feel free to change this guideline so that it will fit the practices more better. I've introduced the noun only to have a possibility to distinguish between Attributes and Relations. — MovGP0 16:55, 10 December 2006 (CET)

Markus said earlier that edits in the Help: namespace, unless they are minor fixes, should be discussed with the developers, since the Help: namespace of ontoworld.org is considered by many as the official docu for SMW. Therefore I use talk pages like this and my user-subpages.--Patrick 00:38, 11 December 2006 (CET)

"[[president of United States from:=1789]] is against the practice of using a noun for the name of an attribute. "President" is a noun, but not one describing the attribute. This name would be more suitable for a relation. Currently we have Relation:Inaugurated as president of the United States in year.--Patrick 08:33, 10 December 2006 (CET)

Using "Inaugurated as president" is ok. Its more precise, even not the way common people would say that in real-world human-to-human talking. Attribute/Relation-Names should be easy to remember, so users don't begin to reinvent the wheel to often.

Anyway, having a Relation instead of an Attribute for Years is only possible if there is a separate Article for each and every year, which is not the case for every wiki.

As attribute name I suggest Attribute:Start date of presidency of the United States, or a more general attribute such as Attribute:Start date for a more specific page, e.g. Presidency of the United States of George Walker Bush.--Patrick 01:05, 11 December 2006 (CET)

Also the Articles describing the Years should also provide their Literal Value as Attribute. At best a year could get expressed as a kind of Date using Wildcards, ie. "xx-xx-1897" is the year without further details to the month or day, while "xx-06-1987" is the sixth month in the same year. Also Wildcards would allow something like "year of birth:=xx-xx-1987", "month of birth:=xx-06-xxxx", and "day of birth:=12-xx-xxxx" all with the same Datatype, so that sorting is more easily done and a construction like "date of birth:= this.day_of_birth + this.month_of_birth + this.year_of_birth" (adding the values of known attributes) will get possible in possible feature releases of SMW.

Therefore I recommend to use Type:Date in the most wikis for such a purpose as described here. — MovGP0 17:56, 10 December 2006 (CET)

It is not clear whether in "Wildcards would allow something like.." you refer to annotations, or queries, or both. I am not sure that usage recommendations can be based on possible future software features. See also User_talk:Skierpage#Type date.--Patrick 00:54, 11 December 2006 (CET)

Is this the Official or Un-Official guideline?

This is an inofficial guideline produced by SMW users. It does not necessarily reflect the opinion of the SMW developers.

I'm not sure what that means. I suspect it means UNofficial, but I could be wrong. Someone please clarify. --Dme 06:47, 2 September 2007 (CEST)
