ckanext-oai-jsonld-harvester

OAI-PMH Harvester for JSON-LD metadata on CKAN, along with Chemistry metadata harvesting.

NFDI4Chem is working on a strategy to harvest metadata using OAI protocol for JSON-LD metadata. This extension provides different harvesting procedures for different Bioschema.Org types which can be later migrated to CKAN database. This also combines two important harvester that have been already developed for NFDI4Chem Search Service, ckanext-oaipmh and ckanext-bioschemaharvester.

Just like the harvester mentioned above, this harvester also uses RDKit python module to generate graphical/imaginary representation of molecules and also other chemi-infomatics.

Currently, it supports two different JSON-LD schemas choosen for harvesting in different hieratical metadata fields followed by their key values mapping with CKAN.

Requirements

Compatibility with core CKAN versions:

Installation

To install ckanext-oai-jsonld-harvester:

1. Activate your CKAN virtual environment, for example:

   . /usr/lib/ckan/default/bin/activate

2. Clone the source and install it on the virtualenv

   git clone https://github.com/bhavin2897/ckanext-oai-jsonld-harvester.git

   cd ckanext-oai-jsonld-harvester

   pip install -e .

   pip install -r requirements.txt

Note: This extension works on RDKit chemi-informatics library which is used to generated molecular information and molecular images during harvesting. And also migration tables are necessary for further database storage.

4. Add massbankharvester t
