[FIXED] How to prepend "./" to a path in a platform independent way?

Issue

I need to prepend ./ to paths in my code, which I'm currently doing like this:

let path = Path::new("foo.sol");
let path_with_dot = Path::new("./").join(path);

However, I want to maintain compatibility across multiple platforms while adding ./ in front of the path. How can I do this?

Solution

A platform dependent const for path separators is stored at std::path::MAIN_SEPARATOR. You can use this to create platform dependent paths. However, by default the Path.join method already uses this const so instead of writing:

let path = Path::new("foo.sol");
let path_with_dot = Path::new("./").join(path);

You would just write:

let path = Path::new("foo.sol");
let path_with_dot = Path::new(".").join(path);

And the result will automatically be platform dependent.

[FIXED] How to list all products in Platform of Trust?

Issue

I'm trying to find an example how to list all data products in Platform of Trust marketplace preferably with a REST API. Is there public API documentation with code examples?

Solution

Yes, the Platform of Trust publishes documentation on the APIs and you can get the list of all available data products via the Product API.

Currently that is via a GET request to their /products/v1/ -endpoint. Host depends on the environment you want to interact with (e.g. https://api-sandbox.oftrust.net for the sandbox environment).

Since this answer is likely going to get eventually out of date, here's a link to that documentation https://docs.oftrust.net/#product-api

[FIXED] Where can I find jsonlds (context) in order to create Products in Platform of Trust?

Issue

Product API documentation has examples for creating data products.

There are parameters dataContext and parameterContext with dummy values as https://example.com/v1/Context/Data.

Where can I find some real context jsonIds for these? I have tried https://api-sandbox.oftrust.net/contexts/v1/ but dataProducts is an empty array there in response.

Are these context specific for translators?

Solution

The values for the contexts are not actually used or checked, so you need to deploy the translator and give the URL to that (and whatever the other mandatory arguments are). We encourage you to consult this multi-connector git repo to see how context of output is configured there to be returned by connector.

DataProducts contexts started to be defined in standards v2 . They are continuously extending based on business needs.

dataContext should have as value the OutputContext

• E.g.: https://standards.oftrust.net/v2/Context/DataProductOutput/Sensor/

parameterContext should have as value the ParametersContext

• E.g.: https://standards.oftrust.net/v2/Context/DataProductParameters/Sensor/
