Subject: Proposed Charter for OASIS XML Interchange Language (XMILE) for System Dynamics Technical Committee


To OASIS Members:

A draft TC charter has been submitted to establish the OASIS XML Interchange Language (XMILE) for System Dynamics Technical Committee. In accordance with the OASIS TC Process Policy section 2.2: (https://www.oasis-open.org/policies-guidelines/tc-process#formation) the proposed charter is hereby submitted for comment. The comment period shall remain open until 6 June 2013 at 23:59 GMT.

OASIS maintains a mailing list for the purpose of submitting comments on proposed charters. Any OASIS member may post to this list by sending email to: oasis-charter-discuss@lists.oasis-open.org. All messages will be publicly archived at: http://lists.oasis-open.org/archives/oasis-charter-discuss/. Members who wish to receive emails must join the group by selecting "join group" on the group home page: http://www.oasis-open.org/apps/org/workgroup/oasis-charter-discuss/. Employees of organizational members do not require primary representative approval to subscribe to the oasis-charter-discuss e-mail.

A telephone conference will be held among the Convener, the OASIS TC Administrator, and those proposers who wish to attend within four days of the close of the comment period. The announcement and call-in information will be noted on the OASIS Charter Discuss Group Calendar.

We encourage member comment and ask that you note the name of the proposed TC (XMILE) in the subject line of your email message.

=== Charter 

(1) Charter for OASIS XML Interchange Language (XMILE) for System Dynamics Technical Committee

(1) (a) Name of the TC

OASIS XML Interchange Language (XMILE) for System Dynamics Technical Committee

(1) (b) Statement of Purpose

The purpose of the XML Interchange Language (XMILE) for System Dynamics (SD) Technical Committee (TC) is to define an open XML protocol for the sharing, interoperability, and reuse of SD models and simulations.  System Dynamics is an interactive environment for simulating the impact of policy on complex ecosystems.  The benefits of this standard are:

- SD models can be re-used with Big Data sets to show how different policies produce different outcomes in complex environments.
- Models can be stored in cloud-based libraries, shared within and between organizations, and used to communicate different outcomes with common vocabulary.
- Model components can be re-used and plugged into other simulations.
- It will allow the creation of online repositories modeling many common business decisions.
- It will increase acceptance and use of System Dynamics as a discipline
- It will help ISVs make new tools that help businesses to develop and understand models and simulations.
- It will enable vendors to develop standards-based applications for new markets such as mobile and social media.

(1) (c) Scope of Work

The TC will accept as input the following SMILE and XMILE specifications published on 2 April 2013:

http://www.iseesystems.com/community/support/SMILEv4.pdf 
http://www.iseesystems.com/community/support/XMILEv4.pdf 

SMILE is a descriptive language based on Dynamo that allows people to create System Dynamic models and components.  XMILE is a specification that encodes SMILE in XML.  

Features of SMILE include:

- A language for simulation of SD models
- A core feature set for representing stock-flow diagrams of SD models

Features of XMILE include:

- A representation for simulation of SD models, in accordance with SMILE, including macro capabilities to both describe and implement vendor-unique language features (level 1)
- A representation of the stock-flow diagrams of SD models, in accordance with SMILE (level 2)
- A representation (level 3) of:
    - Output devices for displaying data, such as graphs and tables,
    - Input devices to allow the building of management flight simulators, and
    - Model and flight simulator annotations such as text boxes and pictures

The TC will refine these initial contributions to produce OASIS Standard versions of the SMILE and XMILE specifications, including necessary supporting documentation.

The scope of the TC’s work is limited to technical refinements to the features defined in the input contributions.  Modest extensions to the SMILE language that substantively increase the interoperability of SD models between vendors, together with their renderings in XMILE, will also be considered.  However, the TC’s main focus is to refine the functionality presented in the input documents.

Out of scope:  Any work not reasonably covered by the Scope of Work is deemed to be out of scope.  Renderings of SMILE that do not use XML are deemed to be out of scope.

SMILE and XMILE contributions to this TC which are out of scope for this charter may be accumulated and taken into consideration for possible inclusion in future subsequent version of the standard.

(1) (d) Deliverables

The TC will produce OASIS Standard versions of both the SMILE and XMILE specifications within 12 to 16 months of the first meeting.  The TC may optionally deliver white papers, orientation materials, tutorials, and such other non-normative content as may be useful to the community.

Maintenance

Once the TC has successfully produced the deliverables, the TC will enter into a maintenance mode.  The purpose of the maintenance mode is to provide minor revisions to previously adopted deliverables, to clarify ambiguities, inconsistencies, and obvious errors.  The maintenance mode will not functionally enhance a previously adopted deliverable, or extend its functionality.

(1) (e) IPR Mode

The committee will operate under the Non-Assertion IPR mode as defined in the OASIS Intellectual Property Rights (IPR) Policy effective 21 June 2012.

(1) (f) Anticipated Audience

The anticipated audience for this work includes:

- Vendors of SD software, Big Data, cloud, mobile, and social media solutions.
- End users of and of the above who implement solutions that require interoperability between SD models and other systems.
- Consultants, educators, and interested parties.

(1) (g) Language

The TC will conduct its business in English.  The output documents will be written in (US) English.

(2) Non-normative information regarding the startup of the TC

(2) (a)  Similar or Applicable Work

XMILE is the XML representation of system dynamics models, as defined in the SMILE language.  As such, it has some overlap with the Systems Biology Markup Language (SBML).  XMILE, however, is specifically tailored to System Dynamics models which are not explicitly represented in SBML.

(2) (b) Date, Time, and Location of First Meeting

The first meeting of the XMILE TC will be a face-to-face meeting to be held at the International System Dynamics Conference, July 24, 2013 in Cambridge, Massachusetts.

(2) (c) On-Going Meeting Plans & Sponsors

It is anticipated that the XMILE TC will meet by teleconference every other week for an hour at a time determined by the TC members during the first TC meeting.  It is anticipated that the XMILE TC will meet face-to-face every 3 months at a time and location to be determined by the TC members.  The actual pace of face-to-face and teleconference meetings will be determined by TC members.  Meetings will be hosted by member companies on a rotating basis.
