Parser and validator library for bioimage.io specifications

Specifications for bioimage.io

This repository contains specifications defined by the bioimage.io community. These specifications are used for defining fields in YAML 1.2 files which should be named rdf.yaml. Such a rdf.yaml --- along with files referenced in it --- can be downloaded from or uploaded to the bioimage.io website and may be produced or consumed by bioimage.io-compatible consumers (e.g. image analysis software like ilastik).

bioimage.io-compatible resources must fulfill the following rules:

Note that the Python package PyYAML does not support YAML 1.2 . We therefore use and recommend ruyaml. For differences see https://ruamelyaml.readthedocs.io/en/latest/pyyaml.

Please also note that the best way to check whether your rdf.yaml file is bioimage.io-compliant is to call bioimageio.core.validate from the bioimageio.core Python package. The bioimageio.core Python package also provides the bioimageio command line interface (CLI) with the validate command:

bioimageio validate path/to/your/rdf.yaml

Format version overview

All bioimage.io description formats are defined as Pydantic models.

type	format version	documentation
model	0.5 0.4	model_spec_v0-5.md model_spec_v0-4.md
dataset	0.3 0.2	dataset_spec_v0-3.md dataset_spec_v0-2.md
notebook	0.3 0.2	notebook_spec_v0-3.md notebook_spec_v0-2.md
application	0.3 0.2	application_spec_v0-3.md application_spec_v0-2.md
collection	0.3 0.2	collection_spec_v0-3.md collection_spec_v0-2.md
generic	0.3 0.2	generic_spec_v0-3.md generic_spec_v0-2.md

JSON schema

Simplified descriptions are available as JSON schema:

bioimageio.spec version	JSON schema
latest	bioimageio_schema_latest.json
0.5	bioimageio_schema_v0-5.json

These are primarily intended for syntax highlighting and form generation.

Examples

We provide some examples for using rdf.yaml files to describe models, applications, notebooks and datasets.

💁 Recommendations

• Due to the limitations of storage services such as Zenodo, which does not support subfolders, it is recommended to place other files in the same directory level of the rdf.yaml file and try to avoid using subdirectories.
• Use the bioimageio.core Python package to validate your rdf.yaml file.
• bioimageio.spec keeps evolving. Try to use and upgrade to the most current format version!

⌨ bioimageio command-line interface (CLI)

The bioimageio CLI has moved entirely to bioimageio.core.

🖥 Installation

bioimageio.spec can be installed with either conda or pip, we recommend to install bioimageio.core instead:

conda install -c conda-forge bioimageio.core

or

pip install -U bioimageio.core
