Re: [SMW-devel] [News] SMW 1.5.0 is near
Thanks Markus that's really good news. I'll keep those restrictions in mind. Really large n-ary properties would anyway be very much the exception. Thanks again for your great SMW effort.

I have now extended the implementation to support "arbitrary" length records. Of course, the length is still restricted by a number of practical considerations. As I explained before, you cannot have arbitrarily long record declarations simply because the space that is available to store the value of "has fields" is limited. This is the same as with "has type" before. Moreover, you cannot have query conditions with large records where all values are constrained in some way because SMW does not allow such large queries by default. You could of course change this setting, but it is not recommended to do this. Since SMW cannot create custom tables for your large records 8this would mean to change the DB schema on the fly), the data is always distributed over many shorter tables, and joining +20 of them slows down MySQL significantly even if they are small and highly selective. Again, this is the same as in earlier versions of SMW. Finally, records that large just look wrong and are hardly unusable in browsing and querying interfaces. Their syntax/display is not tailored toward such sizes, as they were meant to provide short compounds with five or less elements. Anyway, I have tested the code with a 24-field record now and it still works. Regards, Markus > > Cheers, > Gu > > Quoting Markus Krötzsch : > > On Donnerstag, 4.

Re: [SMW-devel] [News] SMW 1.5.0 is near
Hi, well the number of possible fields in n-ary properties is a make or break criteria for me to be able to use MW/SMW, so it's a point I don't dare to lose out of sight. Right now the largest properties I added to the wiki have 15 to 20 fields (but there are potential data with 60+). 'Unlimited' sounds too good to ask for ;) but a number below 20 would certainly not allow me to update. Cheers, Gu Quoting Markus Krötzsch : > On Donnerstag, 4.

Oh, you are very observant. I have left this away since I am not certain yet if I can provide support for records of unlimited size for 1.5.0 or not. If not, then I can only advice users of larger records to not upgrade until a fix has been found.

Re: [SMW-devel] [News] SMW 1.5.0 is near
Hi Markus, http://semantic-mediawiki.org/wiki/Semantic_MediaWiki_1.5.0 doesn't mention any restriction in the number of 'fields' of an n-ary property as it was mentioned in earlier announcements. Has this new limitation been implemented in 1.5 and if so, what is the limit and any advice how to convert larger 1.4 n-ary properties to 1.5?

[SMW-devel] [News] SMW 1.5.0 is near
Hi all, we plan to release SMW 1.5.0 within the next few days. Two or three issues still are on my list for being fixed, but most of the code should be ready now. Moreover, there has just been a new release of Semantic Maps, and there will soon be a release of Semantic Forms. Testers are welcome. I know that many people are running the SVN version anyway, but it may now be a good time to checkout the most recent updates and to confirm that all functions that are important to your wiki are running as expected. Information on how to upgrade can be found on the preliminary release page: http://semantic-mediawiki.org/wiki/Semantic_MediaWiki_1.5.0 Last minute feedback can be sent to this list, or filed to the bugtracker. Translations to the static translation files are also welcome, but we also will have a 1.5.1 release not too long after SMW 1.5.0 to be able to incorporate such improvements.
