SEMANTICS: The subfield of linguistics that studies the meaning of words, parts of words, phrases, sentences and texts. Semantics includes the study of
thematic roles, argument structure, and its linking to
syntax. Semantics deals with
sense and
reference,
truth conditions, and
discourse analysis (wikipedia).

Metadata Semantics: The schema on wich we store metadata about data in an organized fashion and the contents of that metadata repository.
Semantic Web: The Semantic Web is about two things. It is about common formats for interchange of data, where on the original Web we only had interchange of documents. Also it is about language for recording how the data relates to real world objects. That allows a person, or a machine, to start off in one database, and then move through an unending set of databases which are connected not by wires but by being about the same thing. (

ONTOLOGY: In the context of knowledge sharing, I use the term ontology to mean a specification of a conceptualization. That is, an ontology is a description (like a formal specification of a program) of the concepts and relationships that can exist for an agent or a community of agents. This definition is consistent with the usage of ontology as set-of-concept-definitions, but more general. And it is certainly a different sense of the word than its use in philosophy. (

TAXONOMY: The hierarchical organization of data in categories and subcategories or sets and subsets, a XML schema is a very good example of a predefined taxonomy. (or a method for categorizing and organizing content to solve business problems as described by
The Taxonomy Warehouse)
