 ## IDE support
 
-- [Linked Data Extension](https://marketplace.visualstudio.com/items?itemName=Elsevier.linked-data) - VS Code Extension for editing RDF files with embedded SHACL validator and SPARQL engine.
-- [SHACL Language Server](https://marketplace.visualstudio.com/items?itemName=stardog-union.vscode-langserver-shacl) - A VS Code extension providing language intelligence (diagnostics, hover tooltips, auto-completion, etc.) for W3C standard SHACL via the Language Server Protocol.
+These make editing shapes within an IDE like VSCode easier.
