This is a demo query form for the lexical entity inventory.

It is deployed at http://www.perseids.org/tools/lexical

It calls the morphology service at http://services.perseids.org/bsp/morphologyservice

It extracts the lemmas from the response and queries the lexical inventory via the proxy at http://perseids.org/queries/morpheus

This proxy is implemented via a mod_apache rewrite rule

RewriteRule ^/queries/morpheus/(.?)/(.?)$ http://localhost/sparql-proxy/ds/query?query=SELECT+?urn+?replacedby+FROM+<http%3A%2F%2Fdata.perseus.org%2Fds%2Flexical%2Flatlexent>+WHERE+{{?urn+<http%3A%2F%2Fdata.perseus.org%2Frdfvocab%2Flexical%2FhasMorpheusLemma>+"$2"@$1}+UNION+{?urn+<http%3A%2F%2Fdata.perseus.org%2Frdfvocab%2Flexical%2FhasMorpheusLemma>+"$2"@$1.+?urn+<http%3A%2F%2Fpurl.org%2Fdc%2Fterms%2FisReplacedBy>+?replacedby}}&output=xml [P,NE]

Which itself is a request to an apache proxy to fuseki

The results are Lexical Inventory URIs which are retrieved from the CITE Collections service
