CalcyteJS

This is a work-in-progress port of the python-based Calcyte tool.

Status

This is Alpha code.

About

Calcyte is a toolkit to implement the RO-Crate specification:

• Generating HTML from RO-Crate ro-crate-metadata.jsonld files.
• Managing metadata for collections of content via automatically generated spreadsheets (CATALOG.xlsx), to create ro-crate-metadata.jsonld files
• Packaging data in BagIt format, and optionally zipping it.

This version of Calcyte targets the R0-Crate Spec, v1.0.

Installation

NOTE: These instructions are for MacOs - adapt as necessary.

NOTE: Bagit is no longer required!

• Install node.js

• Install Siegfreid using the instructions.

• Get the code:

  git clone --single-branch --branch https://code.research.uts.edu.au/eresearch/CalcyteJS.git

• Link the binary for development use:

  npm link

Usage / instructions

Usage

Calcyfy creates RO-Crates with an HTML entry-point in ro-crate-preview.html file.

Usage:

>  ./calcyfy
   Usage: calcyfy [options] <directories...>

  Generates [RO-Crate] HTML for ro-crate-metadata.jsonld files. Pass a list of directories. To create Spreadsheet files for entering metadata use -d or -r.


  Options:

    -V, --version                    output the version number
    -b,  --bag [bag-dir]             Create Bagit Bag(s) under [bag-dir])
    -n,  --no                        No Citation - only applies ith --bag
    -z,  --zip                       Create a zipped version of the bag - only applies with --bag
    -d,  --depth [depth]             Maximum depth to recurse into directories
    -r,  --recurse                   Recurse into directories looking for CATALOG_.xslx files
    -c,  --cratescript [cratesript]  URL of "crate.js" rendering script from the ro-crate-js library
    -u, --url [distro]               Distribution URL
    -h, --help                       output usage information

To run Calcyte on a group of directories pass it a list of directories

To generate an HTML file for an ro-crate-metadata.jsonld file in ./dir

calcyfy dir

One directory:

calcyfy -r test_data/sample/ 
calcyfy test_data/Glop_Pot -r -c https://data.research.uts.edu.au/examples/ro-crate/examples/src/crate.js

This will:

• Traverse the entire Glop_Pot directory, and generate or update CATALOG_name.xlsx files.
• Create or update the test_data/Glop_Pot/ro-crate-metadata.jsonld`` file
• Create a RO-Crate Website with entry-point test_data/Glop_Pot/ro-crate-metadata.html

All the sample directories:

calcyfy -r test_data/* -c https://data.research.uts.edu.au/examples/ro-crate/examples/src/crate.js

Calcyte will generate:

• a CATALOG_$dir.xlsx file in each directory (this is for humans to fill in with metadata about the data)

• An ro-crate-preview.html file summarizing the data using metadata from CATALOG_$dir.xlsx

• An ro-crate-metadata.jsonld file containing JSON-LD metadata derived from the CATALOG* files plus some basic file-format information.

See the examples in test_data.
