1. General

The Topic Map Query Language (TMQL) is an extension of Structured Query Language (SQL) and Object Query Language (OQL), a query language allowing users to access data in Topic Maps Data Model. TMQL should focus on extending SQL regarding the select-expression language part.

It needs also to extend OQL regarding the tuple-expression language part and the tm-content language part and regarding additional programming support like path epressions. Finally TMQL should consider to follow existing XML query language regarding the xml-content query language part. It is important that the types of data access for Topic Maps, Information retrieval (IR) and information filtering can be supported by the wide number of applications following and extending existing standards such SQL, OQL, XQUERY...

TMQL is intended to be easier to learn by developers, most of whom are likely to already be familiar with SQL. So it would be better to extend TMQL following SQL which was created to be used on the data in a relational database.

Thus the current proposal needs to be updated and revisited accordingly. The major risk is that TMQL might become too complicated to be wildly used and accepted by a large number of applications..

In order to encourage the modification, Japan national body may dispatch a co-editor of this part.

2. Technical

(1) Clause 3.1 Syntax Conventions
The second paragraph in "3.1 Syntax Conventions" says; "The canonical level is defined using context-free grammars (EBNF,[XML 1.0])." And the production rules of TMQL uses the symbols '¨' and ':=='. But there are not '¨' and ':==' in EBNF[XML1.0].

(2) Whole document
The symbols which are used for the shorthand notations are not familiar in the world. They should be explained clearly. And the explanation of the shorthand notations should be enhanced.

3. Editorial

(1) Clause 2 Normative references
Version of Unicode should be 5.0.

(2) Clause 2. Normative references
"IETF RFC 3987, Internationalized Resource Identifiers (IRIs), Internet Standards Track Specification, January 2005, available at <http://www.ietf.org/rfc/rfc3987.txt>" should be added.

(3) Whole the document
"URI" should be changed to "IRI".

(4) Clause 2. Normative references
"XTM 2.0" should be added.

(5) Clause 4.2. Atoms
The datatypes defined by [XML Schema-2] should be allowed.

(6) Clause 4.3 Item References
The term "subject address" should be defined.

(7) Clause 5.4 Special Variables
The term "meta map" should be defined.

(8) Typo
(8.1) Clause 3.1 Syntax Conventions, Clause 4.9 Value Expressions, and Clause Clause 6.6.4 Association Predicates
"explicitely" should be "explicitly"

(8.2) Clause 4.10.3 FORALL Clauses, in the example (2 places)
