The information regarding every family in the discipline addressed, must have a lot in common, known as Metadata. A lot of work has been done in specific domains such as IEEE LOM and MPEG-7 but they...

We introduce a very weak language Lp on Qp, which is just rich enough to have the same definable subsets of the line Qp than one has using the ring language. We prove that the only definable functions in the language Lp are trivial functions. We further give a definitional expansion Lp of Lp in which Qp has quantifier elimination and we obtain a weak cell decomposition. Our language Lp can serv...
