In their particular example, they have an entity 'a shop' and give it the property 'has quay'... but, 'has quay' is not a boolean property, there are qualifications about it (as the article says). It's a case, I think, for fuzzy logic - but how to recognise that in a semantic wiki? Could you have sub-relations to the 'has quay' relation that, collectively give a robust value of 1 if the shop is on the quay and the quay is huge and free for everybody or .1 if it is 500m from the quay and the quay itself is only usable in mid-summer on alternate Fridays?
What do you think?
2013. We will have enterprise and public sector representatives, people from Wikidata, and almost all core developers there! Feel free to propose your talk or the idea for the tutorial on the conference
Semantic MediaWiki (SMW) is a free, open-source extension to MediaWiki – the wiki software that powers Wikipedia – that lets you store and query data within the wiki's pages.
Semantic MediaWiki is also a full-fledged framework, in conjunction with many spinoff extensions, that can turn a wiki into a powerful and flexible “collaborative database”. All data created within SMW can easily be published via the Semantic Web, allowing other systems to use this data seamlessly.
