### Feature Request / Improvement Motivation: https://github.com/apache/iceberg/pull/8907#discussion_r1441986754 Currently there is no relation between [TableMetadata](https://github.com/apache/iceberg/blob/b3273276fa4bac384b2429b7218fd18b242beefe/core/src/main/java/org/apache/iceberg/TableMetadata.java) and [ViewMetadata](https://github.com/apache/iceberg/blob/b3273276fa4bac384b2429b7218fd18b242beefe/core/src/main/java/org/apache/iceberg/view/ViewMetadata.java). Which causes many duplicate codes just to use commonTable/View definitions like Schema/MetadataLocation/Properties. At many places we have similar methods with overloaded parameters like [TableMetadata](https://github.com/apache/iceberg/blob/b3273276fa4bac384b2429b7218fd18b242beefe/core/src/main/java/org/apache/iceberg/TableMetadata.java) and [ViewMetadata](https://github.com/apache/iceberg/blob/b3273276fa4bac384b2429b7218fd18b242beefe/core/src/main/java/org/apache/iceberg/view/ViewMetadata.java). To support [purge](https://github.com/apache/iceberg/issues/9433) on view it is difficult to traverse to the historical metadata files. I would like to start a discussion on potential enhancement of [ViewMetadata](https://github.com/apache/iceberg/blob/b3273276fa4bac384b2429b7218fd18b242beefe/core/src/main/java/org/apache/iceberg/view/ViewMetadata.java). 1. An abstract class such as IcebergMetadata with common definition from [TableMetadata](https://github.com/apache/iceberg/blob/b3273276fa4bac384b2429b7218fd18b242beefe/core/src/main/java/org/apache/iceberg/TableMetadata.java) and [ViewMetadata](https://github.com/apache/iceberg/blob/b3273276fa4bac384b2429b7218fd18b242beefe/core/src/main/java/org/apache/iceberg/view/ViewMetadata.java). 2. Add something similar of [MetadataLogEntry](https://github.com/apache/iceberg/blob/b3273276fa4bac384b2429b7218fd18b242beefe/core/src/main/java/org/apache/iceberg/TableMetadata.java#L195) for [ViewMetadata](https://github.com/apache/iceberg/blob/b3273276fa4bac384b2429b7218fd18b242beefe/core/src/main/java/org/apache/iceberg/view/ViewMetadata.java) too. ### Query engine None -- This is an automated message from the Apache Git Service.
