If you're ready to start that survey re Relational Databases, here's a first submission. n-ary relations are built-in types in the mKR language (http://mKRmKE.org/) Relation tuples are represented as comma-separated values. The unique thing about mKR relations is that they have a built-in context-dependent meaning. The meaning is a list of mKR propositions, with UNIX-shell-style variable substitution. Other attributes of relations may be used to specify automatic declarations, mode (in core or database), etc. Here's a simple example of a relation. address book is relation with format = [person:1, email:2, phone:3], meaning = { $1 has email = $2, phone = $3; }; begin relation address book; John Doe, jdoe@PioneerCA.com, 209-555-1212; Jane Doe, jdoe@unitednations.org, 212-555-1212; end relation address book; Here are some example queries. address book isc* ?; # all tuples ? has email = ?; # all email addresses John Doe has ?; # email & phone Dick ----- Original Message ----- From: "Karl Dubost" <karl@w3.org> To: "Danny Ayers" <danny.ayers@gmail.com> Cc: <semantic-web@w3.org>; "Ivan Herman" <ivan@w3.org>; "Paul Miller" <Paul.Miller@talis.com> Sent: Thursday, June 26, 2008 6:09 PM Subject: Re: "State of the Semantic Web" - personal opinions? > > > Le 27 juin 2008 à 02:20, Danny Ayers a écrit : >> The inspiration - last month I had the pleasure of attending a talk by >> Ivan Herman entitled "State of the Semantic Web" [2] (apologies Ivan, >> the most recent version of your slides I could find online are last >> year's at [3], but I think those carry the gist). > > A bit more recent. > http://www.w3.org/2008/Talks/0307-Tokyo-IH/ > > -- > Karl Dubost - W3C > http://www.w3.org/QA/ > Be Strict To Be Cool > > > > > > > > > Dick McCullough http://mKRmKE.org/ Ayn Rand do speak od mKR done; knowledge := man do identify od existent done; knowledge haspart proposition list; mKE do enhance od "Real Intelligence" done;
