            <title>[UXPROD-4608] Feature: Library of Congress Hub Entity</title>
                <link>https://folio-org.atlassian.net/browse/UXPROD-4608</link>
                <project id="10000" key="UXPROD">UX Product</project>
                    <description>&lt;p&gt;&lt;b&gt;In scope&lt;/b&gt;&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;Baseline Hub from &lt;a href=&quot;http://id.loc.gov&quot; class=&quot;external-link&quot; rel=&quot;nofollow noreferrer&quot;&gt;id.loc.gov&lt;/a&gt; with data graph&lt;/li&gt;
	&lt;li&gt;Ongoing feed to keep the two in sync&lt;/li&gt;
	&lt;li&gt;Index the Hub entries in opensearch for local lookup&lt;/li&gt;
	&lt;li&gt;Support external lookup against id.loc.gov&lt;/li&gt;
	&lt;li&gt;Save when external value selected for resource&lt;/li&gt;
	&lt;li&gt;Update ETL pipeline with Hub algorithm&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Related to UXPROD-4599 - whose scope is limited to executing the Work entity and the Instance entity&lt;/p&gt;

&lt;p&gt;We need to understand the mechanics of how Hubs work in LC&apos;s BF modelling in order to capture the scope and requirements for fulfilling the contractual obligations.&#160;&lt;/p&gt;

&lt;p&gt;Hubs employs the library practice of &apos;collocation&apos; in order to identify definitive works in a collection.&#160;&lt;/p&gt;

&lt;p&gt;&quot;&lt;span class=&quot;error&quot;&gt;&amp;#91;C&amp;#93;&lt;/span&gt;ollocation is attained by clustering item descriptions by . . . authors . . .&#160; and titles. These clusters are done by indexing. Authors&#8217; names may vary, work titles may vary, and work content may vary but bringing together descriptions using different criteria gives the end user the ability to find the most useful resources for their needs.&quot;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&lt;span class=&quot;image-wrap&quot; style=&quot;&quot;&gt;&lt;img src=&quot;/rest/api/3/attachment/content/11179&quot; height=&quot;443&quot; width=&quot;577&quot; style=&quot;border: 0px solid black&quot; /&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Out of scope&lt;/b&gt;&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;BIBFRAME 2 Item entity&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;&lt;b&gt;Use case(s)&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;All components that make up LC&apos;s BIBFRAME 2 Monograph profile must be displayed in production in Marva, inclusive of&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;literals fields&lt;/li&gt;
	&lt;li&gt;lookup fields&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Indexing rules and routines&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;keyword for selected indexes (starting with ISBN, LCCN, Title, Contributor)&lt;/li&gt;
	&lt;li&gt;phrase for supported full text fields (TBD)&lt;/li&gt;
	&lt;li&gt;exact phrase for supported full text fields (TBD)&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;NOTE: will need to determine if the module will support a general keyword index against all (or defined subset of) entity components&lt;/p&gt;

&lt;p&gt;Components treated consistently between BIBFRAME LITE and BIBFRAME 2&lt;/p&gt;

&lt;p&gt;Components treated differently between BIBFRAME LITE and BIBFRAME 2 --&amp;gt; resulting in increased complexity of mapping&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Proposed solution/stories&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Links to additional info&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;Hubs&lt;/p&gt;

&lt;p&gt;&quot;Hubs are abstract resources that function as a bridge between &amp;lt;multiple&amp;gt; Works. In this way, they function as aggregation and collocation resources. They make it possible, for example, to gather all of the &amp;lt;non-English&amp;gt; translations of Mark Twain&#8217;s &lt;em&gt;Tom Sawyer&lt;/em&gt;&#160;or to capture in which other BF Works Francisco Tarrega&#8217;s&#160;&lt;em&gt;Capricho &#225;rabe&lt;/em&gt; are included. &lt;span class=&quot;error&quot;&gt;&amp;#91;H&amp;#93;&lt;/span&gt;ubs perform three functions as aggregators: as subjects, as related works, and as Works in the RDA sense. Hubs, being BF Works, can be used as Subjects to describe other Works.&quot;&lt;/p&gt;

&lt;p&gt;LC recently released version 2.3 of its BIBFRAME ontology. Prior to 2.3, Hubs were defined as a subclass of &apos;Work.&apos; With the release of version 2.3, Hubs have been redefined as one of the ontology&apos;s basic model classes.&#160;&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Questions&lt;/b&gt;&lt;/p&gt;
