Deprecated functionality

Deprecated features are features that Orion stills support but that are not mantained or evolved any longer. In particular:

  • Bugs or issues related with deprecated features and not affecting any other feature are not addressed (they are closed in github.com as soon as they are spotted).
  • Documentation on deprecated features is removed from the repository documentation. Documentation is still available in the documentation set associated to older versions (either in the respository release branches or the pre-0.23.0 documentation in the FIWARE wiki).
  • Deprecated functionality is eventually removed from Orion. Thus you are strongly encouraged to change your implementations using Orion in order not rely on deprecated functionality.

A list of deprecated features and the version in which they were deprecated follows:

  • /ngsi10 and /ngsi9 as URL path prefixes are deprecated in Orion 1.2.0. Please, use /v1 and /v1/registry instead.
  • location metadata to specify entity location is deprecated in Orion 1.1.0. The new way of specifying entity location is to use geo:point type for the attribute (see details in the corresponding section of the user manual.
  • Deprecated command line argument in Orion 0.26.1 (removed in Orion 1.0.0).
  • --silent. Suppress all log output except errors (Please use -logLevel ERROR instead)
  • ONTIMEINTERVAL subscriptions are deprecated since Orion 0.26.0 (removed in Orion 1.0.0). ONTIMEINTERVAL subscriptions have several problems (introduce state in CB, thus making horizontal scaling configuration much harder, and makes it difficult to introduce pagination/filtering). Actually, they aren't really needed, as any use case based on ONTIMEINTERVAL notification can be converted to an equivalent use case in which the receptor runs queryContext at the same frequency (and taking advantage of the features of queryContext, such as pagination or filtering).
  • XML is deprecated since Orion 0.23.0 (removed in Orion 1.0.0).
  • Deprecated command line arguments in Orion 0.21.0 (removed in 0.25.0):
    • -ngsi9. The broker runs only NGSI9 (NGSI10 is not used).
    • -fwdHost . Forwarding host for NGIS9 registerContext when the broker runs in "ConfMan mode".
    • -fwdPort . Forwarding port for NGIS9 registerContext when the broker runs in "ConfMan mode".
  • Configuration Manager role (deprecated in 0.21.0, removed in 0.25.0)
  • Associations (deprecated in 0.21.0, removed in 0.25.0).

Using old Orion versions

Although you are encouraged to use always the newest Orion version, take into account the following information in the case you want to use old versions:

  • Old RPMs (since Orion 0.1.1) are available at the FIWARE yum repository.
  • Code correponding to old releases (since Orion 0.8.1, the first one available as open source) is available at the Orion github repository. Each release number (e.g. 0.23.0) has associated the following:
  • A tag, e.g. 0.23.0. It points to the base version.
  • A release branch, release/0.23.0. The HEAD of this branch usually matches the aforementioned tag. However, if some hotfixes were developed on the base version, this branch contains such hotfixes.
  • Documentation corresponding to old versions can be found:
  • For 0.23.0 and before: documentation is available at FIWARE public wiki (user manual and admin manual).
  • For 0.24.0 or newer: documentation is available at readthedocs.org. Use the panel in the left bottom corner to navigate to the right version.
  • Docker images corresponding to Orion 0.24.0 and newer can be found at Dockerhub.
