Some of this might go a bit far into the implementation details to be part of a first architecture overview. But I plan to say some words about the whole hook/parsing business an the architecture page. > > Best, > > Benedikt > > PS: Can someone tell me: Why does SMWDataValue not have a method > getProperty()? Because it does not have a property. A datavalue is really exactly what is explained on the architecture page: a single value. It represents a number or a wikipage, or whatever. But a property has nothing to do with it (unless the value itself is a property, but this is not what you mean, I think). Semantic statements in SMW a built by combining values. So values are part of the statement, not the other way around. - Markus > > -- > Karlsruhe Institute of Technology (KIT) > Institute of Applied Informatics and Formal Description Methods (AIFB) > > Benedikt Kämpgen > Research Associate > > Kaiserstraße 12 > Building 11.40 > 76131 Karlsruhe, Germany > > Phone: +49 721 608-47946 (!new since 1 January 2011!) > Fax: +49 721 608-46580 (!new since 1 January 2011!) > Email: benedikt.kaemp...@kit.edu > Web: http://www.kit.edu/ > > KIT - University of the State of Baden-Wuerttemberg and > National Research Center of the Helmholtz Association > > > -----Original Message----- > From: Yury Katkov [mailto:katkov.ju...@gmail.com] > Sent: Friday, February 25, 2011 3:11 PM > To: Markus Krötzsch > Cc: SMW developer list > Subject: Re: [SMW-devel] documentation, entry points, interface classes > > Thank you very much, Markus!
