1. Introduction

1.1 URI is the root location of the nfoWorks hierarchy of URI-based identifiers.

1.2 This top level, <>, is not an nfoWorks identifier.  It is simply the unique prefix used in formation of any URI-based nfoWorks identifiers. It can be used as a location and resource the same as the URL of any web page.

1.3 Subfolders lead into an organized hierarchy for identifiers:

namespace {} definition used for illustrative purposes
supplemental and provisional nfoWorks identifiers used in implementations of OpenDocument Format documents.

2. Basic Approach

2.1 This folder organizes definitions of all URI-based identifiers that are introduced by nfoWorks.

2.2 Every URI-based identifier, including namespace identifiers, assigned for nfoWorks has the form <> (with the exact form and capitalizations).

2.3 All nfoWorks-established URI-based identifiers are resolvable to a location in this structure.  The URI leads to the definitive description of the identifier.  Multiple identifiers can be described on the same web page. Distinct identifiers resolving to the same web page will differ in the use of fragment IDs (suffixes following the first "#" in the URI).

2.4 Although every identifier is tied to a unique URI, not every URI resolvable into this structure is an nfoWorks (namespace) identifier.  For example, <> and <> resolve to this section of this page.  No identifier significance is intended beyond providing a reference to a distinct web location (a permalink that serves as a purple number).  The employment of these additional URIs in RDF or any other resolvable reference is not an nfoWorks identifier usage.

2.5 Note: To emphasize when the intended interpretation of a URI text is as a namespace identifier, the notation {text} is used.  When it is useful to delimit URI text without signifying a namespace, the notation <text> is used.  (The {, }, <, and > characters are not allowed in URIs.  They are useful for unambiguously delimiting the extent of a URI that is surrounded by such characters.)

2.6 Additional information about namespaces and URI-based identifiers is provided at [d111001].
