Membership types

  • Q8

    What are the differences between A-, B-, and e-members?

    A-members design and develop specifications of T-Engine and T-Kernel, or of Ubiquitous ID technology. In particular, Executive Committee members are corporations who would like to be deeply involved in the activities of T-Engine Forum.
    B-members promote standardization regarding the promotion of T-Engine. In other words, they are positioned as user members who develop products using T-Engine and T-Kernel.
    e-members are members who promote standardization regarding Ubiquitous ID Center and conduct activities related to applications and feasibility study experiments of Ubiquitous ID technology.

  • Q9

    Does the information members have access to vary according to membership types?

    Yes. Executive Committee members are entitled to receive the IPR policy, licenses, promotions, etc. regarding the whole forum operation and A-members are entitled to receive the relevant technical specifications respectively as they are being designed and drafted. B-members conduct activities based on the designed specification information, but they can obtain such information before it is released to the general public. e-members can receive information on Ubiquitous ID technology and ucode tags as soon as A-members have designed the specifications in the working groups (hereinafter, referred to as "WG"). In other words, members are given different priorities regarding the information received (membership types in order of precedence: Executive Committee members > A-members > B-members, e-members > general public), which means members are given different levels of privileges depending on the membership type..

  • Q10

    What are the differences between B-members and e-members?

    To put it plainly, B-members are involved in "T-Engine and T-Kernel" and e-members are involved in "Ubiquitous ID technology and ucode tags." We made these two different membership types because they handle very different application fields. An organization (or a department) that develops and designs both technologies must become an A-member. If you are in a position to use both technologies, you have to be both a B- and an e-member.

  • Q11

    What are the advantages of being an A-member?

    A-member can:
    (1) Be deeply involved in designing T-Engine specifications.
    (2) Be deeply involved in designing Ubiquitous ID technology specifications.
    (3) Participate in Committee and WGs.
    (4) Obtain information earlier, such as specifications that are being designed and drafted, and production prototypes.
    (5) Have all the privileges that B- and e-member have.

  • Q12

    Our company develops middleware for embedded systems. Which type of membership will be appropriate?

    If your company develops and sells middleware products for T-Engine, A- or B-membership will be appropriate.

  • Q13

    What is EAP available to A- and e-members?

    EAP ( Experimental Activity Procedure ) is a system through which Ubiquitous ID Center supports feasibility study experiments related to ucode tags conducted by A- and e-members of T-Engine Forum.

  • Q14

    Is it possible to change the membership type after becoming a member of T-Engine Forum?

    (1) It is possible to join the forum as a B- or e-member and then to change to an A-member. In this case, you will have to pay the membership fee difference.
    (2) As a rule, changing from a B-member to an e-member, and from an e-member to a B-member is not approved.
    (3) It is possible to join the forum as a B-member and then to join also as an e-member later, or, conversely, to join the forum as an e-member and then to join also as a B-member later. In this case, you will have to pay the additional annual membership fee. Please note that the period of an additional membership fee’s validity conforms to [Q5].

  • Q15

How to obtain specifications and information

  • Q21

    How can we obtain the latest information, specifications, and various other documentations that are released early to the forum members?

    After joining the forum, you can access the "members-only website" for your membership type and obtain information from there.

  • Q22

    Are specifications that are standardized by T-Engine Forum released to the public?

    When specification details are fully fixed, they will be released to the public. However, draft specifications are not released. We aim that specifications standardized by T-Engine Forum will be released eventually, but disclosing them without final editorial work such as removing some ambiguities in the specifications might make it difficult to promote the standardized specifications such as the promotion of products that are similar but not exactly the same. Therefore, draft specifications are released to members only and specification details are checked and fixed after members’ developing and testing prototypes.

  • Q23

    Are standardized specifications and other documents also provided in English?

    All information that is released to the public is provided in English and Japanese. In the future, we will support more languages including Chinese and Korean, depending on the increased number of members and development of overseas offices.

  • Q24

    Can we download information?

    All specifications created by T-Engine Forum can be downloaded. Please note that the levels of information that can be downloaded are varied between members and the general public in accordance with [Q22] above.
