As described in the previous section, JSON-LD was determined to be the metadata format required for the automated evaluation of the digital resource. However, data providers and publishers like wet-lab experimentalists and researchers in the nanosafety domain may not be familiar with this format's technical details. Moreover, learning and practicing its use for daily metadata annotation could be difficult and time-consuming. For the reasons mentioned above, an easy-to-use web application was developed to generate metadata complying with the MRS of choice in JSON-LD format without the need to understand the details of that format. This application is complementary to the maturity indicators within the proposed framework. Then, the generated metadata can be submitted to data repositories, databases, data registries, or any URL on the internet with or without the data. This way, any resource URL that has the generated metadata is qualified for the usability assessment carried out by automated applications. NSDRA metadata generator is a javascript-based front-end module that dynamically generates form-based web interfaces from a maturity indicators' list JSON object. It is able to generate the web form on the fly corresponding to the user's choice of one of the defined maturity indicators lists (i.e., community standards). Moreover, while the user fills the form fields, valid JSON-LD markup is automatically generated and updated with each user interaction with the form. The generated JSON-LD is machine-readable FAIR-compliant metadata that can be automatically assessed using the NSDRA web server application or any other evaluator software capable of consuming JSON-LD format. The app is built using modern web technologies and frameworks HTML5 , CSS3 , Bootstrap 4, and JQuery. The main aim of this app is to assist users, especially experimentalists and wet-lab researchers who have minimal knowledge of semantic web formats, in creating their metadata structure and allowing easier development of linked data compliant markup for data resources.
