Anyone interested in this issue may want to participate in this Tuesday's community call because Scholars Portal will be giving a demo of their new "DDI Explorer" app. For details on how to call in, please see https://groups.google.com/d/msg/dataverse-community/Zpib-uCIG1g/Rg9tJGieBAAJ

The code for Data Explorer by @kevinworthington is at https://github.com/scholarsportal/Dataverse-Data-Explorer and he gave a nice talk about it at the community meeting: https://projects.iq.harvard.edu/dcm2017/agenda .

Thanks for including these links @pdurbin. The latest Data Explorer can be tested at https://scholarsportal.github.io/Dataverse-Data-Explorer/?uri=https://dataverse.scholarsportal.info/api/access/datafile/47298/metadata/ddi&&locale= which includes cross tabulation :)

@kevinworthington cool, I'm having fun playing with my "open source at Harvard" dataset at https://scholarsportal.github.io/Dataverse-Data-Explorer/?uri=https://dataverse.harvard.edu/api/access/datafile/3035125/metadata/ddi . Thanks! 😄

Hi @pdurbin, Glad you like it though the cross-tab feature will not yet work when accessing data for Dataverses other than Scholars Portal. This is due to a AJAX tab file net::ERR_CONTENT_LENGTH_MISMATCH error reported in Jan 31, 2017. The short-term workaround for us was the addition of a servlet to enable loading the tab file columns, found here https://github.com/scholarsportal/SP-dataverse/blob/SP_v4.6.1.1/src/main/java/edu/harvard/iq/dataverse/export/ReadFile.java

Here's a bit better example for playing around https://scholarsportal.github.io/Dataverse-Data-Explorer/?uri=https://dataverse.scholarsportal.info/api/access/datafile/10548/metadata/ddi&&locale=

@kevinworthington This is wonderful! We've been toying with DDI Explorer on a test machine, and after seeing your comment added ReadFile.java to a 4.7 build. Both table- and chart views are working well. Great work!

@kevinworthington thanks for opening #4249 about making your Data Explorer tool available from Dataverse.

I'm not sure what this issue is about anymore. Who is the stakeholder? The FRD linked above hasn't been touched since 2015. Vote to close.

Support for Data Explorer (#4249) was shipped in Dataverse 4.8.6! Closing.
