Hi!
I was wondering how to index nested object into Solr / Goobi viewer?. Let’s say, instead of having structure like this:
"MD_CREATORS" :["Selmer, Marcus ; Berge, Øyvind"]
I would like to have something like:
"actors": [
{
"name": "Selmer, Marcus" ,
"uri": "https://kulturnav.org/e031df43-b0d9-455f-8234-ed428e126b86" ,
"role" : {
"name" : "creator"
}
},
{
"name": "Berge, Øyvind" ,
"uri": "https://kulturnav.org/3f0d2140-9fc4-4972-99ea-eb7c75550094",
"role" : {
"name" : "author"
}
}
]
How do I achieve that? Thank you!

Hi @hemed ,
is the basis for indexing METS/MODS? If yes, can you please provide an example MODS snippet for the two persons you mentioned above?
Cheers,
Jan

Hi @jan ! Thank you for the reply. Please find below the METS/MODS snippet for the persons. You can also see full METS from our test instance here: https://viewer.goobi.ubbe.no/viewer/metsresolver?id=ubb-hru-01
<mods:name type="personal" valueURI="https://kulturnav.org/3af20d5e-3aaf-4efb-b254-a805c3a9aa7e">

Do you visually mean something like this?
This is encoded in MODS the following way:
<mods:name authority="gnd" authorityURI="http://d-nb.info/gnd/" type="personal" valueURI="http://d-nb.info/gnd/101241771">
<mods:role>
<mods:roleTerm authority="marcrelator" type="code">edt</mods:roleTerm>
</mods:role>
<mods:namePart type="family">Plenzat</mods:namePart>
<mods:namePart type="given">Karl</mods:namePart>
<mods:displayForm>Plenzat, Karl</mods:displayForm>
</mods:name>
<mods:name authority="gnd" authorityURI="http://d-nb.info/gnd/" type="personal" valueURI="http://d-nb.info/gnd/116347880">
<mods:role>
<mods:roleTerm authority="marcrelator" type="code">aut</mods:roleTerm>
</mods:role>
<mods:namePart type="family">Eckmann</mods:namePart>
<mods:namePart type="given">Heinrich</mods:namePart>
<mods:displayForm>Eckmann, Heinrich</mods:displayForm>
</mods:name>
The configuration of the Solr field in the solr_indexerconfig.xml is as follows:
<MD_CREATOR>
<list>
<item>
<xpath>
<list>
<item>mets:xmlData/mods:mods/mods:name[@type="personal"][not(mods:role/mods:roleTerm="rcp"[@authority='marcrelator'][@type='code'])]/mods:displayForm</item>
<item>lido:eventActor/lido:actorInRole[lido:roleActor/lido:term]/lido:actor</item>
<item>dc:creator</item>
</list>
</xpath>
<addToDefault>true</addToDefault>
<addSortField>true</addSortField>
<groupEntity type="PERSON">
<!-- MODS -->
<field name="MD_VALUE">mods:displayForm</field>
<field name="MD_DISPLAYFORM">mods:displayForm</field>
<field name="MD_LINK">@xlink:href</field>
<field name="MD_CORPORATION">mods:namePart[not(@type)]</field>
<field name="MD_LASTNAME">mods:namePart[@type="family"]</field>
<field name="MD_FIRSTNAME">mods:namePart[@type="given"]</field>
<field name="MD_LIFEPERIOD">mods:namePart[@type="date"]</field>
<field name="MD_TERMSOFADDRESS">mods:namePart[@type="termsOfAddress"]</field>
<!-- LIDO -->
<field name="MD_VALUE">lido:nameActorSet/lido:appellationValue[@lido:pref="preferred"]</field>
<field name="MD_DISPLAYFORM">lido:nameActorSet/lido:appellationValue[@lido:pref="preferred"]</field>
<field name="MD_DOB">lido:vitalDatesActor/lido:earliestDate[@lido:type="Geburtsdatum"]</field>
<field name="MD_DOD">lido:vitalDatesActor/lido:latestDate[@lido:type="Sterbedatum"]</field>
<field name="NORM_URI">lido:actorID[@lido:source="http://d-nb.info/gnd"]</field>
<!-- DUBLIN CORE -->
<field name="MD_VALUE">text()</field>
<field name="MD_SUBJECT">text()</field>
</groupEntity>
</item>
</list>
</MD_CREATOR>
It is displayed on the metadata page with the following configuration in the config_viewer.xml :
<metadata label="MD_CREATOR" value="MASTERVALUE_SIMPLE_GROUP" group="true">
<param type="field" key="MD_VALUE"/>
<param type="field" key="NORM_WIKIPEDIAURL" value="LINK_WIKIPEDIA_FULL"/>
<param type="normdatauri" key="NORM_URI"/>
<param type="normdatasearch" key="NORM_IDENTIFIER"/>
</metadata>
This are grouped metadata, you can find them in the Solr index when you search with the field PI_TOPSTRUCT instead of PI and combine it with the METADATATYPE:PERSON …
Does this help?
Best,
Jan

Thank you @jan . This looks great, I will try it out!
My usecase was actually to query Goobi viewer from another front-end system. I was therefore interested in getting all metadata from a particular record in JSON format, similar to mainifest API. Is this possible? Otherwise I would have to query Solr directly?
Best regards,

Hi @hemed ,
I don’t think that we have something for your usecase. We usually suggest to work with the IIIF API and we implemented a iiif_simple mode that ignores all resources from files and is faster and simpler, but it still won’t output the information in the desired format.
BUT: You should look at the REST API in case I missed something:
We are open for pull requests, too
