  The paper introduces a tool prototype that combines SHACL's capabilities with
ad-hoc validation functions to create a controlled and user-friendly form
interface for producing valid RDF data. The proposed tool is developed within
the context of the OpenCitations Data Model (OCDM) use case. The paper
discusses the current status of the tool, outlines the future steps required
for achieving full functionality, and explores the potential applications and
benefits of the tool.
