[ink] InkML Implementation Report for Microsoft Office 2010

From: Tom Underhill <Tom.Underhill@microsoft.com>

Message-ID: <4045AB4EE43EB94C9508DDC490FA9F71311A3852@DF-M14-01.exchange.corp.microsoft.com>
Now that the InkML 1.0 specification is in the Candidate Recommendation phase, I am pleased to submit an InkML Implementation Report on behalf of Microsoft for Microsoft Office 2010.

The attached implementation report conforms to the format specified by the InkML 1.0 Implementation Report Plan document (http://www.w3.org/2002/mmi/2011/inkml-irp/).

Below is an HTML form of the attached IR.

Thank you,

Tom Underhill
Software Development Lead at Microsoft Corporation
Editor, Ink Markup Language (InkML) 1.0 Specification


Implementation Name:
Microsoft Office 2010

Testimonial:
Microsoft is committed to incorporating support for natural input into its products. Input methods such as ink handwriting and diagrams expand the types of content that can be created and stored in digital form. The usefulness of such information relies on the ability to create accurate interpretations of the data and the ability to persist these interpretations in an openly accessible format. As a member of the W3C Multimodal Interaction working group, Microsoft supports the Ink Markup Language (InkML) 1.0 Candidate recommendation as an effective approach to representing interpretations of natural input.

The InkML 1.0 standard provides a rich language for expressing the archiving or streaming of digital ink content. A key concern for Microsoft as the company moves to support open file and data exchange formats is that the standards which are ultimately adopted allow for the accurate representation of existing data, typically represented in proprietary binary formats. The proposed InkML standard, along with the related EMMA standard, provides the desired compatibility with existing Microsoft formats. As such, Microsoft believes that the adoption of these specifications will make natural input data available to a broader range of clients, ultimately making such data more useful and valuable.

[3.2.1]<http://www.w3.org/TR/InkML/#trace>

Y

Y

SUB CONSTRAINT: The following grammar defines the syntax of the data that appears within a <trace> element.  It is described using the subset of Extended Backus-Naur Form defined in the Notation section of the Extensible Markup Language (XML) 1.0 (Fourth Edition) specification.  This subset of EBNF includes the following notation:

*: 0 or more
+: 1 or more
?: 0 or 1
(): grouping
|: separates alternatives
double or single quotes surround literals
#x precedes hex character codes
The grammar is as follows:

trace   ::= point ("," point)* ","? wsp*

point   ::= (wsp* value)+ wsp*

value   ::= difference_order?  wsp* "-"? wsp* number | "T" | "F" | "*" | "?"

number  ::= (decimal | double | hex)

double  ::= decimal ("e"|"E") ("+"|"-")? digit+

decimal ::= digit+ ("." digit*)? | "." digit+

hex     ::= "#" (digit | "A" | "B" | "C" | "D" | "E" | "F")+

difference_order ::= ("!" | "'" | '"')

digit   ::= ("0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9")

wsp     ::= (#x20 | #x9 | #xD | #xA)
Additionally, wsp may occur anywhere except within a decimal, float or hex and must occur if required to separate two values. Otherwise the longest token is matched. For example, "3245" requires an internal wsp character if it is to be interpreted as two decimal numbers, "32" and "45". On the other hand, "0.923.45" will be interpreted as "0.923" and ".45".
