<p>Hi again,</p>
<p><br>
</p>
<p>I did a quick check. If you run the populate script, it will create a mappe and a saksmappe.</p>
<p><br>
</p>
<p><span>A GET on a series that has both mappe and saksmappe e.g. <a href="http://localhost:8092/noark5v4/hateoas-api/arkivstruktur/arkivdel/6f650057-352d-4446-87f9-ca19d8accbaa/mappe" class="OWAAutoLink" id="LPlnk155812" previewremoved="true">http://localhost:8092/noark5v4/hateoas-api/arkivstruktur/arkivdel/6f650057-352d-4446-87f9-ca19d8accbaa/mappe</a></span><br>
</p>
<p><br>
</p>
<p><span style="font-size: 12pt;">will return a list of mappe. If you look at the self rels</span><br>
</p>
<p><b><br>
</b></p>
<p><b>For mappe they will be:</b></p>
<p><span>"href" : "http://localhost:8092/noark5v4/hateoas-api/arkivstruktur/mappe/c66f1e92-5ece-45db-acaa-a2f88c59d822/"</span><br>
</p>
<p><span><b><br>
</b></span></p>
<p><span><b>For saksmappe they will be:</b></span></p>
<p><span></span></p>
<div><span style="font-size: 12pt;">"href" : "http://localhost:8092/noark5v4/hateoas-api/sakarkiv/saksmappe/1d7610f4-9bb0-4044-959d-4e79ab86a228/",</span><br>
</div>
<div><br>
</div>
<p></p>
<p>So it is possible to filter out saksmappe. We do however still need to be able to just retrieve saksmappe from arkivdel.</p>

<p>I have considered this and wondered if saksmappe and moetemappe should not be part of the mappe list. It comes down to how inheritance is handled in the core.</p>
<p><br>
</p>
<p>If inheritance is joined, mappe exists as a table and moetmappe and saksmappe link back to the mappe table. In essence the record is distributed across two tables and most CRUD operations will require a SQL join. This is what nikita does.</p>
<p><br>
</p>
<p>The other strategy is a table per entity, where there is just a moetemappe and saksmappe table. There is no mappe table. In this case a call to find all mappe would require processing of saksmappe and moetemappe on their own.</p>
<p><br>
</p>
<p>My understanding of the spec is that joined is the underlying method they hint at is to use joined. </p>
<p><br>
</p>
<p>I thought it was possible to filter out saksmappe when you get all mappe. If the entity is a mappe, then it will use arkivstruktur/mappe, but if the entity is a saksmappe it will use sakarkiv/saksmappe. This should be visible now and was one of the things
that was fixed when I did the big anti-pattern update.</p>

Using the API, is there a well known way to figure the class of an<br>
entity? I have not seen it described in the spec. It might remove the<br>
need for a .../arkivdel/<id>/saksmappe endpoint, as I could instead use<br>
the .../arkivdel/<id>/mappe endpoint and filter out entities without the<br>
saksmappe class.<br>
<br>
When looking at <URL: <a href="http://n5test.kxml.no/api/arkivstruktur/mappe" id="LPlnk592631" previewremoved="true">
http://n5test.kxml.no/api/arkivstruktur/mappe</a> >, I<br>
notice this trick which could be used to identify the class of 'self':<br>
<br>
"_links":[<br>
{<br>
"rel":"self",<br>
"href":"http://n5test.kxml.no/api/arkivstruktur/Mappe/37a8f68c-a9d3-4af2-b547-4fa95e36e70e",<br>
"templated":false<br>
}, {<br>
"rel":"http://rel.kxml.no/noark5/v4/api/arkivstruktur/mappe",<br>
"href":"http://n5test.kxml.no/api/arkivstruktur/Mappe/37a8f68c-a9d3-4af2-b547-4fa95e36e70e",<br>
"templated":false<br>
}, ...<br>
<br>
Here you can see that the 'self' link have a href that is identical to<br>
another href, and the rel of that href represent the class of the<br>
entity.<br>
<br>
Did I miss the description in the spec stating that this is the way to<br>
detect the entity class, or should we write a defect report suggesting<br>
how to figure out the class of a entity?<br>

Happy hacking<br>
