rdf_has_bdb

<p>Detect whether Berkeley Database for disk-based storage of RDF graphs
is available.  Disk-based storage requires redland package
to be installed from source with support for the Berkeley DB
(libdb-dev on Ubuntu, berkeley-db on homebrew), otherwise <code>rdf()</code> will
fall back to in-memory storage with a warning.</p>

The Resource Description Framework, or 'RDF' is a widely used
data representation model that forms the cornerstone of the
Semantic Web. 'RDF' represents data as a graph rather than
the familiar data table or rectangle of relational databases.
The 'rdflib' package provides a friendly and concise user interface
for performing common tasks on 'RDF' data, such as reading, writing
and converting between the various serializations of 'RDF' data,
including 'rdfxml', 'turtle', 'nquads', 'ntriples', and 'json-ld';
creating new 'RDF' graphs, and performing graph queries using 'SPARQL'.
This package wraps the low level 'redland' R package which
provides direct bindings to the 'redland' C library.  Additionally,
the package supports the newer and more developer friendly
'JSON-LD' format through the 'jsonld' package. The package
interface takes inspiration from the Python 'rdflib' library.
