Greetings, I wanted to discuss here some proposed changes to the elasticgeo plugin related to handling multiple valid date formats, as reported in [GEOT-6577] <https://osgeo-org.atlassian.net/browse/GEOT-6577>.
As I've mentioned in the ticket, the core reason this issue is happening is that the DataStore expects there to be just one valid date format, and that is what it will use for the attribute. Elasticsearch is not as strict, and permits mappings of multiple valid date formats for an index, meaning we can get data with different date formats for the same attribute. To allow this functionality, I plan to change the dateFormat to a List of String objects, and rename it to validDateFormats. When reading the feature, just iterate through the List looking for a date format which matches the data value. When the data store is parsing the date format from elastic, the List will be assigned to the format received, split on each ||. I welcome input on the design here, if there's a more reasonable way to accomplish this. Cheers, Travis
