+Package: maplibr
+Title: R Interface to the 'maplib' Knowledge Graph Engine
+Version: 0.0.0.9000
+Authors@R: c(
+    person("Novica", "Nakov", , "nnovica@gmail.com", role = c("aut", "cre", "cph"),
+           comment = c(ORCID = "0009-0005-7773-7718")))
+Description: Build, query, and reason over RDF knowledge graphs backed by the
+    'maplib' Rust engine. Graphs are constructed from tabular data using OTTR
+    mapping templates, queried with SPARQL, and returned as ordinary R
+    data frames via the Arrow C Stream Interface. Also supports RDFS
+    inference and reading/writing common RDF serializations (Turtle,
+    N-Triples, RDF/XML).
