# What is OpenMetadata?
[OpenMetadata](https://open-metadata.org/) is an Open Standard for Metadata. A Single place to Discover, Collaborate, and Get your data right.
[OpenMetadata](https://open-metadata.org/) is an all-in-one platform for data discovery, data lineage, data quality, observability, governance, and team collaboration. It is one of the fastest growing open-source projects with a vibrant community and adoption by a diverse set of companies in a variety of industry verticals. Powered by a centralized metadata store based on Open Metadata Standards/APIs, supporting connectors to a wide range of data services, OpenMetadata enables end-to-end metadata management, giving you the freedom to unlock the value of your data assets.
