Standards Committee

Table of Contents Standards Committee








The goal of the Standards Committee is to foster increased coordination and direction in our common community effort to develop a better LDraw file format. The participants of this body will discuss, vote on, and adopt community-developed commands as Official standards, consisting of the original LDraw spec (1.0.0) plus meta-commands developed by various LDraw-compatible LEGO CAD programs.


The LDraw community has existed as a minimally organized group of users, programmers, and parts authors since James Jessiman’s LDraw became widely used in the mid 1990’s. This community originated solely online and continues to use the internet as it’s primary medium of communication. LDraw standards have until this point only been semi-organized as well, with individual leaders in file format issues, but no defined processes for format evolution. This has caused confusion among both newcomers and long time participants, and the community recognizes the need for a group charged with adopting official standards and publishing official documentation.

Responsibilities of the Standards Committee

The Standards Committee (LSC) will be responsible for maintaining semi-regular internal discussions on pending file format issues, the overall progress of the LDraw file format and new or proposed developments made by different LDraw-based software authors. This group will be responsible for developing their own internal procedures on how to process and vote on proposals and how to write and publish documentation. The Committee will also be responsible for updating the greater LDraw community periodically of progress within the group. The Standards Committee will adopt new official standards by voting on them, and publish documentation on following such a decision. The LSC will document past, current and future LDraw File Formats.


The procedures shall be determined by the LSC itself. Items that shall be attended to include (but are not limited to):

  • Call for internal discussion on a proposal made internally (by another LSC member) or externally (by a member of the LDraw Community)
  • Request for Final Comments (RFC) from the community before a vote
  • Call for a vote to ratify a proposal as standard
  • Drafting, reviewing, and publishing spec documents
  • Procedure for filling an early vacancy of a member
  • Number of votes needed to accept a proposal as a standard
  • Appointing sub-committees

Each LSC member can cast one (1) vote on any issue brought up within the LSC.


Membership of the LSC shall have a minimum of 5 people. The LSC can vote to create additional vacancies for future elections. The LSC also defines a procedure for voting to eliminate seats added in the future. One seat is reserved for a current LDraw Library Administrator. If there is more than one LDraw Library Administrator then the LDraw Library Administrators will self select a member to represent them on the LSC.

Requirements for LSC Membership

To ensure only competent, dedicated, and active contributors are eligible to become members of the LSC, they shall have met one or more of the following requirements for nomination:

  • Authored at least two LDraw parts subsequently released in an Official Parts Update
  • Served as a reviewer on the Parts Tracker through at least 2 official parts updates, and posted at least 5 reviews in at least two updates since their initial participation
  • Released a still available software program that is compliant with either the LDraw 1.0.0 spec or another spec published by the LSC
  • Petition for nomination as an LSC candidate approved by 2 current LSC members
  • Petition for nomination as an LSC candidate made to the LSC by at least 5 others eligible to be LSC candidates

In the event that an Official Parts Update has not been released for more than six months the following criteria substitute the activity on the LDraw Parts Tracker listed above:

  • Authored at least two LDraw parts which have been submitted to the Parts Tracker and subsequently marked Certified
  • Served as a reviewer on the Parts Tracker for at least one year, and posted at least 5 reviews in that year
LSC Discussion

The LSC shall have a mailing list or other communication method where only members can post, but the entire community can read. This allows the community to keep tabs on what is being discussed, and discuss LSC issues in public forums such as LUGNET’s CAD.* groups. The LSC should encourage this discussion, and should draw ideas and suggestions from non-LSC members in the community, ensuring everyone’s voice is heard. However, the LSC shall be the only group that votes to ratify a proposal as a standard.

Annual Summary

The members of the LSC will be responsible for publishing an annual summary to the community several weeks prior elections for the next year’s term. This summary shall outline the progress of the previous term, note all versions of the spec ratified during the term, and summarize the future goals and ideas of the current LSC members.


Terms on the Standards Committee lasts one year.


The Steering Committee will call for nominations to the Standards Committee on the first day of October of that year. Nominations must be received and recorded by the 14th of October. Nominees must have accept or decline the nomination by the 17th of October. People can either self-nominate or nominate someone else. The nomination must reference the candidates eligibility from the list above.


Only LDraw organization members will vote on the nominees by privately listing the five (5) nominees they select for the position. Votes will be received and tallied by the Steering Commitee, who will be accountable to each other and to the community for accuracy. The LSC will consist of no more than 5 people, however the LSC will be able to create vacant seats to be filled at a future election if they wish. Elections will begin on the 17th of October and end October 31.

The current Steering Commitee will announce the results of the election within 6 days of the election, on or before November 7.


Elected members of the LSC will take office on November 15. This gives downtime for outgoing members and incoming members to discuss the published Annual Report and ensure a smooth transition.
