ipldm: The InterPlanetary Linked Data Model and codec formats.
Provides the IPLD data model in an abstract form with the different IPLD data kinds. Also codecs for decoding these kinds from serialized formats such as DAG-CBOR, and encoding the abstract data model back into binary formats.

Readme for ipldm-1.0.0.0
[back to package description]ipldm 
The ipldm library provides methods for working with the IPLD data model (DM) in Haskell. Disclaimer that this project
is still in alpha, and not ready to be used in a production system.
Currently, the project has the following functionalities:
- Represeting the DM with nodes of
some kind including CIDs provided by the
mfmtspackage. - A type-class interface for implementing generic encoders and decoders for the DM using Alternatives.
- Implements codec for DAG-CBOR with encoder/decoder instances that work with CBOR encoded bytestrings and provides exeptions for formatting errors and IPLD's extra constraints.
Development
Unit tests are provided on the main ipfshs repo, and bugs can be reported on ipfshs ticket tracker.
Licensing
The ipldm project and its modules are free software and licensed under the
AGPLv3 license. See
LICENSE.txt.
