space and time
Hi All, Apologies for the cross-posting (I come in peace, with free stuff) Some time ago Simon suggested that there might be some measures which should be taken with regard to historical time frames and the Julian Calendar. IIRC, this is something Chris asked me, some time ago, to do as well. The general problem is: once you have overshot the target by you don't know how much, how much do you back up ? The computation is not Quantum Mechanics or GPS, it is Linear Algebra (on intervals) and the shape of the frequency bin (box or circle in 2D, no other choices). This problem comes up with Calendars frequently since there is no way to un-Integrate fractional time. I wrote a DB of Calendar Quarters for the Julian Century (1950 - 2050). Anyone is welcome to it. There are XML and SQL versions. Other formats are a possibility. http://www.rustprivacy.org/2014/balance/quads/ The same algebra (matrix decomposition by fours) also applies to Unicodes and Acronyms for Government work where the rdfs:label / of the elements in a Code Page does not change from quarter to quarter, year to year, century to century etc., but also for the money handling (accounting) aspects of Government. In the US, Revenue Collection is in Spring and the Fiscal Year starts in Fall - I use the quotes not because this is an American system but rather because Downunder, the Equinox labels mean different things. It is sort of a strange idea: Unicodes and Acronyms have no right to be forgotten. --Gannon
Attribute or Property Ontology?
Hi All, I have been looking for an ontology that organizes and describes possible characteristics or attributes for common entity types, such as what might be found in a key-value pair in Wikipedia infoboxes and such. I have had no luck finding such a vocabulary or ontology. The closest representation I found was one related to sensors and the Internet of Things (IoT) [1]. The Wolfram Language also has an interesting structure around units [2]. Biperpedia has recently been discussed by Google [3], but no actual ontology or structure yet appears available for inspection. Does anyone know of a general ontology for capturing record/entity attributes or characteristics (properties)? I know some domains like biomedical may have partial approaches to this, but I'm seeking something that has as its intent being a general-purpose attribute reference. Suggestions or pointers would be greatly appreciated. Thanks, Mike [1] http://eprints.eemcs.utwente.nl/23734/01/CICARE2013_-_Brandt_et_al_-_Semantic_interoperability_in_sensor_applications_-_final_version.pdf [2] http://reference.wolfram.com/language/guide/Units.html [3] http://infolab.stanford.edu/~euijong/biperpedia.pdf

Re: Attribute or Property Ontology?
Hi David, Yes, thanks, it was an oversight not to mention QUDT. Sorry, Ralph, this is a valuable resource, and we have used it in the past. But, per my more general interests, its scope of units of measurement does not capture the broad extent of attributes and characterizations. What I am finding perplexing is that we have many examples of upper ontologies and such to describe the concepts of the world and their relationships (the TBox), but apparently have no similar sources for attributes or properties (the ABox).
