Alfonso Nishikawa commented on GORA-557:
----------------------------------------

Hi, [~mariia.podorvanova].

Here is some documentation about the metadata analyzer: 
https://translate.google.com/translate?sl=es&tl=en&u=https://redmine.nishilua.com/projects/goraexplorer/wiki/Obtenci%25C3%25B3n_de_metadatos_de_las_BBDD_nativas
 (I Googletranslated it from Spanish).
One of the constructors of DataStoreMetadataFactory receives a Properties 
(that, probably, will be gora.properties or set by code), and as you say, 
DataStoreMetadataAnalyzer does not seems to have that field. Probably you have 
a good reason to add that field at DataStoreMetadataAnalyzer and populate it 
when the factory instantiates a MongoDB analyzer :)

> After merging GoraExplorer interfaces and methods for the core, MongoDB 
> module has to be updated with the following:
> - Allow to load mappings from properties instead only from files. [Example at 
> HBaseStore|https://github.com/apache/gora/blob/6ce47dcdea60e4b0d3abe03ddac01a65716cc173/gora-hbase/src/main/java/org/apache/gora/hbase/store/HBaseStore.java#L145]
>  (where the static final constant much probably will have to be refactorized).
> - Implement the retrieval of native information from MongoDB. ([Technical 
> details|https://translate.google.es/translate?sl=es&tl=en&js=y&prev=_t&hl=es&ie=UTF-8&u=http%3A%2F%2Fredmine.nishilua.com%2Fprojects%2Fgoraexplorer%2Fwiki%2FObtenci%25C3%25B3n_de_metadatos_de_las_BBDD_nativas&edit-text=])
> A plus would be implement the support in 
> [GoraExplorer|https://www.goraexplorer.com] so it will be possible to manage 
> MongoDB data visually.
