Thoughts on Solr Indexing

I have got the JSON-LDs in the MongoDB and the next step is to push them to Solr. Solr requires a schema to provide a room for the coming data. I will discuss my approach towards indexing data in Soor here -

Before we proceed, let me give a sample of what our data looks like - { "@context":"http://schema.org", "@type":"DataRecord", "identifier":"biosamples:SAMEA103996091",`` "datasetPartOf":{ `"@type":"Dataset",` `"@id":"https://www.ebi.ac.uk/biosamples/samples"` `},` `"isPartOf":{` `"@type":"Dataset",` `"@id":"https://www.ebi.ac.uk/biosamples/samples"` `},` `"dateModified":"2018-01-20T13:42:43.039Z",` `"dateCreated":"2016-08-30T23:00:00Z",` `"mainEntity":{` `"dataset":[` `"http://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-4567"` `],` `"@context":"http://schema.org",` `"@type":[` `"BioChemEntity",` `"Sample"` `],` `"name":"source hESC-H9-primed_3",` `"url":"https://www.ebi.ac.uk/biosamples/sample/SAMEA103996091",` `"identifiers":[` `"biosamples:SAMEA103996091"` `],` `"additionalProperty":[` `{` `"name":"Organism",` `"value":"Homo sapiens",` `"valueReference":[` `{` `"url":"http://purl.obolibrary.org/obo/NCBITaxon_9606",` `"@type":"CategoryCode"` `}` `],` `"@type":"PropertyValue"` `},` `{` `"name":"cell line",` `"value":"H9",` `"valueReference":[` `{` `"url":"http://www.ebi.ac.uk/efo/EFO_0003045",` `"@type":"CategoryCode"` `}` `],` `"@type":"PropertyValue"` `},` `{` `"name":"cell type",` `"value":"embryonic stem cell",` `"valueReference":[` `{` `"url":"http://purl.obolibrary.org/obo/CL_0002322",` `"@type":"CategoryCode"` `}` `],` `"@type":"PropertyValue"` `},` `{` `"name":"genetic modification",` `"value":"transfected with doxycycline inducible MCRS1, THAP11, TET1 construct",` `"@type":"PropertyValue"` `},` `{` `"name":"growth condition",` `"value":"W8 media",` `"@type":"PropertyValue"` `},` `{` `"name":"phenotype",` `"value":"primed pluripotent state",` `"@type":"PropertyValue"` `}` `]` `}` `}`

Let us break this nested JSON-LD in parts -
