DOL — Cleanup of encoding and markups

Because of its original source, many of the definitions and comments contain Latex markup and symbols that are not properly encoded. This needs to be cleaned up.

Encoding corrected, latex annotations removed

non-UTF 8 symbols were replaced by UTF 8 symbols (e.g., non-UTF quotation marks).
Latex markup was replaced by equivalent text. Citations were removed, since they are available in the specification text.

For example the following text:

AnnotationAssertion(<http://www.w3.org/2004/02/skos/core#note> <http://www.omg.org/spec/DOL/DOL-terms/LinkedData> " The linked data principles (adapted from
cite

and its paraphrase at
cite

) are the following:
begin

"@en)

was replaced by

AnnotationAssertion(<http://www.w3.org/2004/02/skos/core#note> <http://www.omg.org/spec/DOL/DOL-terms/LinkedData> "Linked data principles, as interpreted herein, are as follows: (a) Use IRIs as names for things; (b) Use HTTP IRIs so that these things can be referred to and looked up (dereferenced) by people and user agents; i.e., the IRI is treated as a URL (uniform resource locator); (c) Provide useful machine-processable (plus optionally human-readable) information about the thing when its IRI is dereferenced, using standard formats; (d) Include links to other, related IRIs in the exposed data to improve discovery of other related information on the Web."^^xsd:string)

Note that change from language tagged strings to xsd:string is the result of the resolution of ticket DOL-102

The OWL file is attached to the resolution of DOL-102. The resolution does not affect the specification.
