-SpatialData is a data framework that comprises a FAIR storage format and a collection of python libraries for performant access, alignment, and processing of uni- and multi-modal spatial omics datasets. This repository contains the core spatialdata library. See the links below to learn more about other packages in the SpatialData ecosystem.
+SpatialData is a data framework, a schema and a serialization format for uni- and multi-modal spatial omics datasets. It is supported by a growing suite of software libraries for performant access, manipulation and analysis in multiple languages, including Python, R and JavaScript.
