+`vo-models` is an open-source project to provide Python models for [IVOA](https://www.ivoa.net/) service protocols.
 
 The project is designed to be used by IVOA members, service implementors, and developers to help facilitate the development of IVOA-compliant services and clients.
 
 ## Features
 
 - **Pydantic-xml Models:** The project includes Python models for IVOA protocols, using [pydantic-xml](https://github.com/dapper91/pydantic-xml). Based on [Pydantic](https://docs.pydantic.dev/latest/), these models describe transactions for an IVOA protocol, such as UWS, and feature automatic validation, parsing and serialization of XML data for use with Python clients and web frameworks.
 
-- **Expandability:** The project is designed with future expansion in mind. Plans include extending the schema and models to cover other IVOA standards.

-### Pydantic-XML Models
-
-Python models using [pydantic-xml](https://github.com/dapper91/pydantic-xml), a library based on [Pydantic](https://docs.pydantic.dev/latest/), are provided in the `vo/models/xml` directory.
-
-These models can be used to parse and validate XML data into Python objects, as well as serialize Python objects into XML data. These models can be used with any Python web framework, but are particularly useful when used libraries that leverage the power of Pydantic, such as [FastAPI](https://fastapi.tiangolo.com/).

 ### Contributing
 
 Contributions to the project are more than welcome. Collaboration and discussion with other IVOA members, service implementors, and developers is what started this project, and is what makes the IVOA great.
