## Tools

[Plecos](https://github.com/oceanprotocol/plecos) is a Python tool to check metadata (a JSON file) to see if it conforms to the [OEP8 schema](https://github.com/oceanprotocol/OEPs/tree/master/8). Plecos wraps the [jsonschema](https://github.com/Julian/jsonschema) validator.

Users can use Plecos to check their metadata before sending it to an Aquarius instance. Plecos is manually updated with a schema file according to [OEP8](https://github.com/oceanprotocol/OEPs/tree/master/8). Find the tool in [PyPI](https://pypi.org/project/plecos/).

Plecos can be used in a microservice to facilitate data onboarding, as described in the [plecos_service](https://github.com/oceanprotocol/plecos_service) repository.
