# CIC schemas
|
|
|
|
This project aims to contain sufficient tools for generation, validation and packaging of metadata describing impacts and externalities from the use of Community Inclusion Currencies (CICs).
|
|
|
|
The expression of impacts and externalities will henceforth be referred to as _certifications_.
|
|
|
|
_This is a work in process. It is in alpha state, and may radically change at any time._
|
|
|
|
|
|
## Using the project
|
|
|
|
To build json schemas and run tests, please install the python dependencies in `requirements.txt`:
|
|
|
|
`pip install -r requirements.txt`
|
|
|
|
(You may want to use a virtual environment)
|
|
|
|
|
|
## Structure
|
|
|
|
Each unit of metadata consists of two parts:
|
|
|
|
1. RDF documents the certifications of vouchers, accounts and transactions.
|
|
|
|
2. A JSON metadata structure bundlinf certficiations as tradeable NFTs.
|
|
|
|
NFT tooling is at the current time intended for EVM blockchains only.
|
|
|
|
|
|
## Certification vocaularies
|
|
|
|
Four base vocabularies are used to define the certifications.
|
|
|
|
* [`foaf`](http://xmlns.com/foaf/0.1/) - well-known library used to describe human resources and relationships.
|
|
* `evm` - EVM specific resources like transactions and account addresses.
|
|
* `cic` - concepts specific to CICs, e.g. _Unit of Account_, _voucher validity_ and other parameters decribing kinds of economic activity.
|
|
* `ge` - subject Impact types and areas of interest, according to Grassroots Economics - the organization pioneering this work.
|
|
|
|
|
|
### Including other vocabularies
|
|
|
|
Authors of certifications may express impacts and externalities in vocuabularies managed by themselves or other interested parties.
|
|
|
|
For example, Grassroots Economics can author a certification with the fictious **We Do Good NGO** as intended recipient. When doing so, elements from the `wedogood` vocabulary is used to reference specific points of interest in terms recognized by the recipient's systems.
|
|
|
|
`wedogood` can furthermore be a vocabulary that systems of the fictious **We Do More Good NGO** trusts and recognizes, which in turn can improve reliability and confidence for them.
|
|
|
|
|
|
### Files
|
|
|
|
Example certification files used for initial development are (`test_tx.rdf` and `test_voucher.rdf`).
|
|
|
|
Note these schemas are not yet defined. They only exist as fictious references in the example files.
|
|
|
|
|
|
## EVM NFT
|
|
|
|
The JSON metadata implements the **ERC721** standard, as well as parts of the **Opensea** metadata standard.
|
|
|
|
It also contains immutable references to one or more certifications which the NFT represents.
|
|
|
|
Apart from the `certifications` field, data in the JSON structure is only intended for purposes of displaying the NFT in a user interface.
|
|
|
|
|
|
### Files
|
|
|
|
Current state of the JSON schema can be found in `dist/cic.json`. It is composed by the `build.py` script from `*.in.json`.
|
|
|
|
`test_valid.json` is a single example data file used to test the JSON schema. `make test` builds the schema and runs the
|
|
|
|
|
|
|
|
### The attribute property
|
|
|
|
The `attributes` property may contain one or more values that represents parameters within certifications. However, it does not represent the autoritative data.
|
|
|
|
Care must be taken to make sure the display parameters does not conflict with the data defined in the certification itself.
