The yotta Public Registry

When you use yotta publish to publish your re-usable modules, they are uploaded to the yotta public registry.

They are immediately available to find via search online, and via the yotta search subcommand, and for anyone to install as a dependency of their own project.

# Module Ownership

Before you can publish a module (or a target description), yotta will ask you to log in. When you do, your email address(es) from the account you log in with on the webpage are associated with the keys stored in your local yotta settings.

These keys are used to sign requests made to the registry, proving to the registry that you control the email address in question. This allows you to publish updates to the same module in the future: if you switch to a different computer then you’ll need to log in again to regain access to publish your modules.

To remove the stored keys from your settings, use the yotta logout command.

The yotta owners subcommands (yotta owners list, yotta owner add and yotta owner remove) allow you to add or remove other people (by email address) from those allowed to publish new versions (and modify ownership) of your modules and targets.

## # Network Access In order to use the yotta registry, yotta needs access to several different domains, which host various parts of the registry infrastructure. You may need to allow access to these domains though your firewall:

  • the registry API itself
  • the blob store where versions of modules and targets are downloaded from.
  • necessary for the login mechanism.

Note that all of these domains may use multiple IP addresses, and each may share their IP addresses with other domains.

# Disputes and Names

Please open an issue on the Github issue tracker for any disputes arising over module ownership. Do not publish an empty module in order to “reserve” a name for your future use - either implement something useful, or let someone else do the same. If someone else wants to publish a useful module under a name you have published only an empty module to then ownership of your module will be granted to them.

If you use a trademark belonging to a company in your module name (e.g. a silicon vendor’s name) and that company later wants to support their hardware or software in yotta, you may be asked to let them contribute to your module, or take over maintenance of it.

To take over ownership of a module abandoned by its owner please open an issue on Github, it is likely that these requests will be granted if contact cannot be re-established with the owner within a reasonable amount of time.

# Terms of Use

The yotta registry is for yotta modules (that’s software that can usefully be used with other yotta modules to build an application for at least one target). yotta modules can support any target hardware (ARM or otherwise), but we reserve the right to remove anything from the registry which isn’t a useful yotta module.

The mbed terms of use apply to your use of the yotta registry, and the content you upload.
