### Feature Request / Improvement Today, numerous catalogs have emerged, each with its own specifications for table creation, metadata refreshing, and implementing data governance rules. This diversity has led to increased complexity and confusion, making it challenging for users to choose the right catalog. To address this challenge, we previously proposed an [RFC](https://github.com/apache/incubator-xtable/pull/605/files) for synchronizing table format metadata across catalogs. An access control policy defines a rule stating, "A principal has specific privileges for a securable object." In the context of data catalogs, these privileges can include actions like SELECT or CREATE statements used in DDL, DML, or DQL queries, the securable objects can range from databases and tables to columns and beyond. When a catalog is connected to a query engine, it enforces these permissions for the principal (user) either directly or by issuing temporary credentials that the query engine can use to execute queries securely. In today’s data ecosystem, numerous catalogs exist, each with its own specifications and methods for enforcing access control policies. Some catalogs, like AWS Glue and BigLake, are tightly integrated within their ecosystems, while others rely on credential-sharing approaches to support multiple query engines. Similar to how we have defined [InternalTable](https://github.com/apache/incubator-xtable/blob/main/xtable-api/src/main/java/org/apache/xtable/model/InternalTable.java), we aim to establish a canonical representation for access control policies and synchronize these policies across different catalogs. ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
