; Abstract:
; The Open Data Protocol (OData) enables the creation of REST-based data
; services, which allow resources, identified using Uniform Resource
; Identifiers (URLs) and defined in a data model, to be published and
; edited by Web clients using simple HTTP messages. This document defines
; the URL syntax for requests and the serialization format for primitive
; literals in request and response payloads.
;
; Overview:
; This grammar uses the ABNF defined in RFC5234 with one extension: literals
; enclosed in single quotes (e.g. '$metadata') are treated case-sensitive.
;
; The following rules assume that URIs have been percent-encoding normalized
; as described in section 6.2.2.2 of RFC3986
; (http://tools.ietf.org/html/rfc3986#section-6.2.2.2)
; before applying the grammar to them, i.e. all characters in the unreserved
; set (see rule "unreserved" below) are plain literals and NOT
; percent-encoded.
;
; For characters outside the unreserved set the rules explicitly state
; whether the percent-encoded representation is treated identical to the
; plain literal representation.
;
; One prominent example is the single quote that delimits OData primitive
; type literals: %27 and ' are treated identically, so a single quote within
; a string literal is "encoded" as two consecutive single quotes in either
; literal or percent-encoded representation.
;
; Contents:
; 1. Resource Path
; 2. Query Options
; 3. Context URL Fragments
; 4. Expressions
; 5. JSON format for function parameters
; 6. Names and identifiers
; 7. Literal Data Values
; 8. Header values
; 9. Punctuation
;
; A. URI syntax [RFC3986]
; B. IRI syntax [RFC3986]
; C. ABNF core definitions [RFC5234]
