- [GH_Chunk.ChunkKeyedCollection](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk.chunkkeyedcollection.md): Represents a collection of chunks with associated IDs
- [GH_Compression](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-compression.md): Provides static methods for compression of byte-arrays.
- [GH_LooseChunk](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-loosechunk.md): A utility class for creating partial archives.
- [GH_Message](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-message.md): Represents an archive log message. Messages are collected during read/write operations.
