Hmmm ... Another Beer Friday in der Schweiz :-) Actually I did have a comment on Domains and URLs mapping to RESTful URI's, and bending has quite a bit to do with it, and another thread ... Re: How to model valid time of resource properties? Yesterday, Frans Knibbe suggested a "small example" might clear up some modelling pitfalls. The problem, I think, haunts tools and capabilities in SPARQL and SQL and the modelling problems can be and should be cleaned up at that level. Towit: SPARQL queries do not *always* generate the trace (diagonal) of an identity matrix necessary (per Group Theory) to solve differential equations. An SQL INNER JOIN does not *always* generate the trace either. If the trace is modelled with an SQL OUTER JOIN then the trace can be found. This is "dot" notation. Unicode Code Planes "just work" because they are 4 digits of a trace. Spreadsheets "just work" because ... well, they don't unless you make sure that base 26 numerical identifiers exclude all the linear combinations except the trace. This is the nature of throwing and catching meta data - detecting side-band noise and ignoring it. RDF is processed recursively so the model (you) is responsible for this detection/un-selection. Long story short ... a couple of demonstrations of RDF Local Codes on the real number/time line/unit circle. 1) http://www.rustprivacy.org/faca/rdf-list/Unicodes-Unicodes.ods 2) http://www.rustprivacy.org/faca/rdf-list/Spreadsheet-Unicodes.ods 1) Is Four Base 16 digits (range 256) 2) Is Two Base 26 digits (range 676) Look at Columns M-R on the first page. Note that the "selection" does not contain the entire range and that *neither* "first" or "last" codes are the same set as "trace". Next look at the table B24-G28 on the second page. Note that the number base (range) "distribution" statistics change depending on Group Selection. Wow, there must be an art to writing good Linked Data Apps.

Do you? * Do URIs dream of HTTP? * Where do URIs go when its HTTP response is 410? -Sarven http://csarven.ca/#i
