# MultiReferenceFileSystem An fsspec filesystem that extends Kerchunk's ``ReferenceFileSystem`` with multi-range byte fetching. This is used internally by the Zarr codec pipeline to read JPEG 2000 codestreams with interleaved tile-parts that span non-contiguous byte ranges in a single file. ```{note} `fsspec` is an optional dependency. This class is available when `pip install osml-imagery-io[zarr]` is installed. ``` ```{eval-rst} .. autoclass:: aws.osml.io.multi_reference_fs.MultiReferenceFileSystem :members: :undoc-members: :show-inheritance: ```
