+      <description>&amp;ldquo;RDF Binary&amp;rdquo; is a efficient format for RDF and RDF-related data using Apache Thrift or Google Protocol Buffers as the binary data encoding.
 The W3C standard RDF syntaxes are text or XML based. These incur costs in parsing; the most human-readable formats also incur high costs to write, and have limited scalability due to the need to analyse the data for pretty printing rather than simply stream to output.
 Binary formats are faster to process - they do not incur the parsing costs of text-base formats.</description>

+<p>Jena provides a single interface, <a href="../rdfconnection"><code>RDFConnection</code></a> for
+working with local and remote RDF data using these protocols in a unified way.
+This is most useful for remote data because the setup to connect is more
+complicated and can be done once and reused.</p>
+<p>HTTP Authentication is provided for remote operations.</p>
+<p>Applications can also use the various execution engines through
+<code>QueryExecution</code>, <code>UpdateExecution</code> and <code>ModelStore</code>.</p>
+<p>All the main implementations work at &ldquo;Graph SPI&rdquo; (GPI) level and an application
+may wish to work with this lower level interface that implements generalized RDF
+(i.e. a triple is any three nodes, including ones like variables, and subsystem
+extension nodes).</p>
+<p>The GPI version is the main machinery working at the storage and network level,
+and the API version is an adapter to convert to the Model API and related
+classes.</p>
+<p>This documentation describes the API classes - the GPI companion classes are the
+same style, sometimes with slightly changed naming.</p>
+<p><code>UpdateProcessor</code> is a legacy name for <code>UpdateExecution</code></p>
+<p><code>GSP</code> provides the SPARQL Graph Store Protocol, including extensions for sending
+and receiving datasets, rather than individual graphs.</p>
+<p>Both API and GPI provide builders for detailed setup, particularly for remote
+usage over HTTP and HTTPS where detailed control of the HTTP requests is
+sometimes necessary to work with other triple stores.</p>
+<p>HTTP authentication support is provided, supporting both basic and digest
+authentication in challenge-response scenarios.</p>
+<p>Factory style functions for many common usage patterns are retained in
+<code>QueryExecutionFactory</code>, <code>UpdateExecutionFactory</code>.</p>
+<h2 id="changes">Changes from Jena 4.2.0 to Jena 4.3.0</h2>
+<ul>
+<li>
+<p>Execution objects have a companion builder. This is especially important of
+HTTP as there many configuration options that may be needed. Local use is
+still covered by the existing <code>QueryExecutionFactory</code> as well as the new
+<code>QueryExecutionBuilder</code>.</p>
+</li>
+<li>
+<p>HTTP usage provided by the JDK <code>java.net.http</code> package, with challenge-based
+authentication provided on top by Jena. <a href="#auth">See below</a>.</p>
+</li>
+<li>
+<p>Authentication support is uniformly applied to query, update, GSP and <code>SERVICE</code>.</p>
+</li>
+<li>
+<p>HTTP/2 support</p>
+</li>
+<li>
+<p>Remove Apache HttpClient usage</p>
+<ul>
+<li>When using this for authentication, application code changes wil be
+necessary.</li>
+</ul>
+</li>
+<li>
+<p>Deprecate modifying <code>QueryExecution</code> after it is built.</p>
+</li>
+<li>
+<p>Parameterization for remote queries.
+Parameterization - replacing variables by values before sending
+a query - makes the query into a template. The same applies to updates.</p>
+</li>
+<li>
+<p><code>HttpOp</code> is split into <code>HttpRDF</code> for GET/POST/PUT/DELETE of graphs and
+datasets and new <code>HttpOp</code> for packaged-up common patterns of HTTP usage.</p>
+</li>
+<li>
+<p>DatasetAccessors removed.</p>
+</li>
+<li>
+<p>GSP - support for dataset operations as well as graphs (also supported by Fuseki).</p>

+</code></pre></div><p>The <code>RegistryRequestModifier</code> registry is checked on each HTTP operation. It
+maps URLs or prefix of URLs to a function of interface <code>HttpRequestModifier</code>
+which has access to the headers and the query string parameters of the request.</p>
+<h2 id="auth">Authentication</h2>
+<p>For any use of users-password information, and especially HTTP basic
+authentication, information is visible in the HTTP headers. Using HTTPS is
+necessary to avoid snooping.  Digest authentication is also stronger over HTTPS
+because it protects against man-in-the-middle attacks.</p>
+<p>There are 5 variations:</p>
+<ol>
+<li>Basic authentication</li>
+<li>Challenge-Basic authentication</li>
+<li>Challenge-Digest authentication</li>
+<li>URL user (that is, <code>user@host.net</code> in the URL)</li>
+<li>URL user and password in the URL (that is, <code>user:password@host.net</code> in the URL)</li>
+</ol>
+<p>Basic authentication occurs where the app provides the users and password
+information to the JDK <code>HttpClient</code> and that information is always used when
+sending HTTP requests with that <code>HttpClient</code>. It does not require an initial
+request-challenge-resend to initiate. This is provided natively by the <code>java.net.http</code>
+JDK code. See <code>HttpClient.newBuilder().authenticate(...)</code>.</p>
+<p>Challenge based authentication, for &ldquo;basic&rdquo; or &ldquo;digest&rdquo;, are provided by Jena.
+The challenge happens on the first contact with the remote endpoint and the
+server returns a 401 response with an HTTP header saying which style of
+authentication is required. There is a registry of users name and password for
+endpoints which is consulted and the appropriate
+<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Authorization"><code>Authorization:</code></a>
+header is generated then the request resent. If no registration matches, the 401
+is passed back to the application as an exception.</p>
+<p>Because it is a challenge response to a request, the request must be sent twice,
+first to trigger the challenge and then again with the HTTP authentication
+information.  To make this automatic, the first request must not be a streaming
+request (the stream is not repeatable). All HTTP request generated by Jena are
+repeatable.</p>
+<p>The URL can contain a <code>userinfo</code> part, either the <code>users@host</code> form, or the <code>user:password@host</code> form.
+If just the user is given, the authentication environment is consulted for registered users-password information. If user and password is given, the details as given are used. This latter form is not recommended and should only be used if necessary because the password is in-clear in the SPARQL
+query.</p>

+      <description>&amp;ldquo;RDF Binary&amp;rdquo; is a efficient format for RDF and RDF-related data using Apache Thrift or Google Protocol Buffers as the binary data encoding.
 The W3C standard RDF syntaxes are text or XML based. These incur costs in parsing; the most human-readable formats also incur high costs to write, and have limited scalability due to the need to analyse the data for pretty printing rather than simply stream to output.
 Binary formats are faster to process - they do not incur the parsing costs of text-base formats.</description>
