lodex-update-model v1.0.0

node-lodex-update-model

Script to create a model from an older version of LODEX.

Motivation

When you create a LODEX instance for the first time, you generally use AUTOGENERATE_URI (except when you already got URIs). You create a model by picking columns in the original tabular data, applying transformers or not.

When you want to update the LODEX version, you have to create a new instance, using that new version of LODEX. You then have two options:

1. loading original tabular data again
2. exporting data from first LODEX instance, and loading it to the new one

Each option has its drawback:

1. You have to manage the URI, by no more auto-generating it. That means you have to modify the original data, by manually copy-pasting the generated URI into a new column.
2. You have to manually simplify the model:
   • no more auto-generate, simpling using a column value,
   • if you ignored original columns in the first LODEX instance, you'll have to point to the right column again, for each column.

This script will use the second option, to export the old model, modify it so that the URI is no more autogenerated, and so that all columns point to the right one.

Usage

$ lodex-update-model model.json > new-model.json
