Procurement: Development of RyderEx

[hugi]

Brief: New Graphryder

We are developing a new version of Graphryder. We describe the scope of this application here:

Graphryder (RyderEx) experiments

This thread is for coordination around the new experimental Graphryder and coordinating with collaborators. To not confuse this with the old codebase, we will call this experimental version “RyderEx” for the time being. In brief, the architecture of RyderEx is as follows: Import An import script connects directly to the Postgres database of any number of Discourse platforms with the Edgeryders OpenEthnographer extension and imports all conversational and ethnographic content from those platform…

This work is a deliverable of the POPREBEL project (WP2, Task 2.5), funded through the European Union’s Horizon 2020 research and innovation programme under grant agreement No 822682.

Requirements

Technology stack:

• Neo4j
• Sigma.js
• Graphology
• GraphQL
• Node.js

Extensive and proven experience with all of the technologies in the stack is crucial. Applicants must have delivered complex graph visualization applications for web browsers using this stack in the past.

Bounty

We are offering 10,000 EUR, paid on delivery.

Licensing

All code should be published under AGPLv3.

How to apply

• Post here, along with links to some of your work.
• A decision will be made within 14 days.

Dear EdgeRyders community, dear Hugi,

I cofounded together with Alexis Jacomy and Benoît Simard, OuestWare a french software dev agency specialized in data-driven web applications. We would like to propose our services for the Graphryder new version development as we think we have the perfect team to help you out on this.

I have a 10-years experience working with social scientists to analyze research data. Long ago, I developed a qualitative research data archive prototype with the BeQuali research team: beQuali - index
I also worked a lot with graph in various research contexts :

• FOSDEM 2016 - Modeling a Philosophical Inquiry: from MySQL to a graph database
• FOSDEM 2015 - Manylines
• FOSDEM 2019 - Using networks to study 18th century French trade

Alexis created sigma.js which is already used by your platform. We are working on sigma.js version 2 release which benefits natively from the graphology ecosystem. He more generally excels at designing and developing high end data visualization interactive web applications.

Benoît has a 10-years experience working for Neo4J. Full-stack developer, he masters the full chain from the database to the web front and definitely knows about graphs.

Your project falls perfectly into our skills set and in the kind of project we like to do: open source tool for researchers using graph technologies. From our recent references, let me pinpoint a few:

• a CMDB application base on graph exploration : OuestWare - Our productions
• a bibliometry web application : OuestWare - Our productions

Finally, note that using GraphQL, react and Neo4J is something we know and promote: GRAND Stack: One schema to rule them all

We would be very happy to work with you on this project.

Best regards,

Paul, Alexis and Benoît
