- Wef the signature = has an arrow expression (s s)?k then I= must map Ds?Ds to Dk.
The effect of datatypes. If dt ? DTS, let LSdt denote the lexical space of dt, VSdt denote its value space, and Ldt: LSdt > VSdt the lexical-to-value-space mapping. Then the following must hold:
- VSdt ? D; and
- For each constant "illuminated"^^dt such that lit ? LSdt, IC("lit"^^dt) = Ldt(lit).
RIF-FLD does not impose special requirements on IC for constants in the symbol spaces that do not correspond to the identifiers of the datatypes in DTS. Dialects ple of such a restriction could be a requirement that no constant in a particular symbol space (such as rif:local) can be mapped to VSdt of a datatype dt.
step three.5 Annotations and Official Semantics
RIF-FLD annotations are stripped before the mappings that constitute RIF-FLD semantic structures are applied. Likewise, they are stripped before applying the knowledge valuation, TValI, defined in the next section. Thus, identifiers and metadata have no effect on the formal semantics.
Note that in the event annotations of this RIF-FLD algorithms are ignored of the semantics, they’re removed because of the XML systems. Given that annotations try represented by the frame terms, they truly are reasoned with of the regulations. The latest frame terminology used to depict metadata are able to getting fed to many other algorithms, ergo helping cause throughout the metadata. But not, RIF does not explain people concrete semantics to possess metadata.
step three.6 Translation away from Low-file Algorithms
This section defines how a semantic structure, I, determines the truth value TValI(?) of a RIF-FLD formula, ?, where ? is any formula other than a document formula or a remote formula. Truth valuation of document formulas is defined in the next section.
To this end, we define a mapping, TValI, from the set of all non-document formulas to TV. Note that the definition implies that TValI(? Continue reading "New datatype identifiers for the DTS enforce next limits"
