An interesting read on the challenges related to vulnerability indices https://link.springer.com/article/10.1007/s10113-023-02033-2

What is the context or reason for the change?
The current V schema (v 0.1) is a very bare-bone version of the original Mover proposal, which consists of 4 modules addressing the range of possible approaches for the vulnerability component.
The Mover schema originally had hundreds of fields and specifications, most of which are quite specific and optional, ultimately rarely found in the kind of risk screening world bank produces. In comparison, other schemas had 1/4 the number of fields.
Why is this not covered by the existing model?
The Mover schema is able to accomodate a very complex model with a wide range of variables and parameters, something that is not unheard of when discussing building-level risk assessment for some types of hazards e.g. earthquakes. Hover, in the current status of risk screening and assessment, most of the time vulnerability (impact) models for natural hazards come in the form of step-value tables and/or mathematical functions. This is true for agencies report and for academic research alike. For this reason, we started with a generalised version that is fit to represent a set of representative vulnerability model that we can leverage at the moment.
In v0.1, the VLN schema has been simplified to cover primarily two purposes:
accomodate the typical physical vulnerability model (Component 1 of original Mover)
What is your proposed change?
In version 2, we also want to include another sub-component of the VLN schema to describe socio-economic vulnerability (Component 3 of original Mover).
Moreover, the V-1 sub-component could be extended to include more details about the function - similarly to what has been done for CAPRA model functions (example below). This needs further investigations, in particular about the format of data.
Suggesting to start fitting it on a selection of vulnerability models to use as showcase data. In terms of sources, the following can be investigated:
Can you provide an example?
Optional. If possible, provide a snippet of data that illustrates how your proposed changes would be used. This might be a link to an existing dataset.
