Re: Welcome to the community group on Bridging GraphQL and RDF

Hi, all.

My name is Sergio Rodríguez.  As a Software Engineer with over 20+ years of
experience, I have been working in integrating systems across government
and industry projects.  I hold a Ph.D. in Computer Science from NCTU
(Taiwan) where I focused on developing the Brain-Computer Interaction (BCI)
Ontology along with a Federated Linked Big Data semantic layer for a
pervasive Augmented-BCI system.  Currently, I'm a Postdoctoral Research
Fellow at The Australian National University working on Knowledge Graph
(KG) Engineering, leading the software development on building a KG for
government contextual document-metadata.  As part of our tasks, our backend
services (KG "engine") will need to manage/translate/perform client-side
(tools) requests to server-side executions (various kinds of data sources).

Clearly, a clean layer/interface of GraphQL-to-SPARQL mappings based on
SHACLs and OWL ontologies is the desired approach in our architecture.  I'm
interested in participating in this CG in order to have fruitful technical
discussions that could lead to developing a "standardized approach" and lay
down best-practices.
