1        Introduction

Moving Picture, Audio and Data Coding by Artificial Intelligence (MPAI) is an international non-profit organisation with the mission of developing standards for Artificial Intelligence (AI)-enabled digital data coding and technologies that facilitate the integration of data coding components into ICT systems [1]. With the mechanism of Framework Licences, MPAI intends to facilitate the creation of a patent pool that relies on the clear IPR licensing frameworks established by the Framework Licences [2].

AI Framework Version 1 (MPAI-AIF V1) is an MPAI System-oriented standard specifying an environment able to execute AI applications called AI Workflows (AIW) composed of AI Modules (AIM).

MPAI Application Standards normatively specify the Function of the AIW and its AIMs, the Syntax and Semantics of the input and output Data of the AIW and its AIMs, and the Connections between and among the AIMs of an AIW. MPAI Application Standards do not specify the internal architecture of the AIMs, which may be based on AI or data processing technologies, and be implemented in software, hardware or mixed software and hardware technologies.

MPAI-AIF V1 assumes that the execution environment is in a Trusted Zone. However, it does not specify how an environment with the required attributes can be realised. Therefore, MPAI has developed a set of Functional Requirements whose satisfaction can support the developer with specific security requirements.

This MPAI-AIF V2 Call for Technologies (CfT) invites any party owning technologies that satisfy the MPAI-AIF V2 Use Cases and Functional Requirements [5] and are willing to release their technologies to any third party according to the MPAI-AIF V2 Framework Licence [6], if selected by MPAI and inclusion in the MPAI-AIF V2 standard with possible modifications. Any respondent party who is not an MPAI member and has their technologies accepted shall join MPAI or lose the opportunity to have their technologies included.

The MPAI-AIF V2 Technical Specification will be developed using technologies that are:

  1. Part of an already published MPAI standard, or
  2. Satisfy the following mandatory requirements:
    1. To be part of responses to this Call containing acceptance of the MPAI-AIF V2 Framework Licence [6].
    2. To satisfy the MPAI-AIF V2 Use Cases and Functional Requirements [5]. In the future, MPAI may decide to further extend MPAI-AIF to support new functionalities as a part of this MPAI-AIF V2 or as a future extension of it.
    3. To use, where feasible and desirable, the technologies in the MPAI-AIF V1.1 standard [4] that satisfy MPAI-AIF V2 Use Cases and Functional Requirements [5] or the technologies specified in other relevant MPAI standards published in [1].

Therefore, the scope of this Call for Technologies includes technologies satisfying the requirements identified in [5].

However, respondents are welcome to additionally do one or more of the following:

  1. Make comments on any technology or architectural component identified in [5].
  2. Propose to:
  3. Add or remove input/output signals to the identified AIMs:
    1. Justifying the changes.
    2. Identifying the data formats of the new input/output data.
  1. Partition the AIMs in an AIW implementing the cases providing:
  1. Arguments in support of the proposed partitioning.
  2. Detailed specifications of the input and output data of the proposed new AIMs.
  1. New fully described Use Cases as done in [5].
  1. In general, submit motivated proposals of technologies not included in [5], for inclusion in the MPAI-AIF V2 standard MPAI if they satisfy the Framework Licence [6].

All parties who believe they have relevant technologies satisfying all or most of the requirements of [5] are invited to submit proposals for consideration by MPAI. MPAI membership is not a prerequisite for responding to this CfT. However, proponents should be aware that, if their proposal or part thereof is accepted for inclusion in the MPAI-AIF V2 standard, they will be requested to immediately join MPAI, or lose the opportunity to have their accepted technologies included in the standard.

MPAI will select the most suitable technologies based on their technical merits for inclusion in the MPAI-AIF V2 standard after possible adaptation/modification. However, MPAI in not obligated, by virtue of this CfT, to select a particular technology or to select any of the proposed technologies if those submitted are found inadequate.

Submissions shall be received to the MPAI secretariat (secretariat@mpai.community) by 2021/10/10 T23:59 UTC. The secretariat will acknowledge receipt of the submission via email. Submissions will be reviewed according to the schedule that the 25th MPAI General Assembly (MPAI-25) will define at its online meeting on 2021/10/12. For details on how non MPAI members who have made a submission can attend the said review sessions should contact the MPAI secretariat (secretariat@mpai.community).

2        How to submit a response

Those planning to respond to this CfT are:

  1. Advised that online event has been held on 2022/07/11 at 15:00 UTC where the MPAI-AIF V2 Functional Requirements were presented. The recording of the presentation is available [7].
  2. Requested to communicate their intention to respond to this MPAI-AIF V2 CfT with an initial version of the form of Annex A to the MPAI secretariat (secretariat@mpai.community) by 2021/09/13. Submission of Annex A helps MPAI properly plan for the revision of submissions. However, those who have submitted an Annex A are not requested to make a submission and those who have not submitted Annex A are not precluded from making a submission.
  3. Encouraged to visit regularly the Call for Technologies web page where additional relevant information will be posted.

Responses to this MPAI-AIF V2 CfT may or shall include:

Table 1 – Optional and mandatory elements of a response

Table 4 – Explanation of submission features

Submission features Criteria
Completeness of description Evaluators should

1.     Compare the list of requirements (Annex C of the CfT) with the submission.

2.     Check if respondents have described in sufficient detail to what part of the requirements their proposal refers to.

NB1: Completeness of a proposal for a Use Case is a merit because reviewers can assess how the components are integrated.

NB2: Submissions will be judged for the merit of what is proposed. A submission on a single technology that is excellent may be considered instead of a submission that is complete but has a less performing technology.

Understandability Evaluators should identify items that are demonstrably unclear (incon­sistencies, sentences with dubious meaning etc.)
Extensibility Evaluators should check if respondent has proposed extensions.

NB: Extensibility is the capability of the proposed solution to support functionalities that are not supported by current requirements.

Use of standard Technology Evaluators should check if new technologies are proposed where widely adopted technologies exist. If this is the case, the merit of the new technology shall be proved.
Efficiency Evaluators should assess power consumption, computational speed, computational complexity.
Test cases Evaluators should report whether a proposal contains suggestions for testing the technologies proposed.
Maturity of reference implementation Evaluators should assess the maturity of the proposal.

Note 1: Maturity is measured by the completeness, i.e., having all the necessary information and appropriate parts of the HW/SW implementation of the submission disclosed.

Note 2: If there are parts of the implementation that are not disclosed but demonstrated, they will be considered if and only if such components are replicable.

Relative complexity Evaluators should identify issues that would make it difficult to implement the proposal compared to the state of the art.
Support of MPAI-AIF use cases Evaluators should check how many use cases are supported in the submission
Support of non MPAI-AIF use cases Evaluators should check whether the technologies proposed can demonstrably be used in other significantly different use cases.
