Other Open PRs

PR #89: Remove multi-sim text

  • Multi-SIM support is not well-understood and should be "solved" for all CAMARA APIs.

  • Multi-SIM support was discussed in several CAMARA API subprojects without solution.

  • For interoperability reasons API providers should handle the Multi-SIM case in the same manner.

MEETING UPDATES

:

  • Eric Murray to propose more generic text describing different options for multi-SIM scenario handling

:

  • Alternative wording proposed in this comment

:

  • No more update on this to add alternative description and looking for comment from Axel Nennker to proceed further.

PR #92: Use scopes and introduce a pairwise pseudonymous identifier

  • This PR proposes two changes to the API definition:

    • Introduction of a third device identifier ppid, which is a pairwise pseudonymous identifier for the device
    • Control of fields included in the response by individual scopes, rather than by a single scope covering all possible response fields

MEETING UPDATES

:

  • Discussion:
    • PPID as third device identifier is fine, but should be introduced as additional endpoint rather than controlling through scopes
    • A better description of the properties of a PPID is required, in addition to the external link
      • For example, if a new SIM (from the same MNO) is used in the physical device, should the PPID be re-generated?
  • Eric Murray to comment in PR

:

  • Cannot now be merged before Spring'25 meta-release. Leave open in case Axel Nennker wants to revise. Otherwise raise new issue on PPID introduction following Spring'25 meta-release.

:

  • No more update on this. Axel Nennker should share his thought on this.

Issues

Closed Issues

  • Issue #95: Should the 429 error response be documented in the YAML?

    • 429 errors are now no longer mandatory in the OAS definition
    • We do document 429 errors. Should we keep them?

MEETING UPDATES

:

  • No view expressed either way during meeting. Leave open for comments until PR #94 is merged, and then close if no comments.

:

  • No view expressed. Keeping 429 errors in YAML for now. Issue closed.

  • Issue #100: Description of 403 PERMISSION_DENIED error is outdated

    • Current text in info.description for `403 PERMISSION_DENIED" is as follows:

      If the end user has not consented to the API consumer getting access to the device identifier information, then a 403 PERMISSION_DENIED error is returned.

      This is only true for a 2-legged access token (i.e. client credentials), and is not the only reason for this error. More generally, for both 2- and 3-legged access tokens, this error would be returned if the access token did not have the correct scope for the endpoint being called.

    • Updated error description text proposed in PR #101

Discussion #36: Alternative device identifiers

  • An alternative proposal is to salt the IMEI with an API consumer specific salt and then hash it
  • This would a less useful identifier (only useful to the API consumer) but easier to justify providing under an opt-out or no consent basis
  • Use cases for such an alternative identifier are not clear

MEETING UPDATES:

:

  • Discussion updated by Axel Nennker with proposal to include PPID as a 3rd device identifier that can be requested (in addition to IMEI or TAC)

:

  • Axel Nennker to review and make proposal for additional physical device identifier

:

:

  • No update

:

  • Discussion has been updated. Please review.
