As a first try, I've updated an extract of data for 5 days, to this next.openspending platform.
Here's my experience with OpenSpending:
1) There are several fields for which I had to choose "Unknown":
a) transaction description. Unfortunately, this field is unstructured and contains raw description with specifying classification codes, contract identifiers, budgetary codes, court orders, etc in a single raw string. Can OpenSpending in any way help with parsing those raw description fields and extracting valuable information?
b) recipient bank (name and code). I couldn't find whether I can specify which bank the money goes
c) payer bank (name and code). Similarly, apparently there's no field dedicated to payer's bank account
2) When I visualize recipient, I see its identifier, but not its display name.
3) When I edit the dataset, it looks like that date format is not saved, it's always "%Y-%m-%d".
4) I couldn't find a way to enrich my dataset with some external resources. I found that there is some "external hooks" feature. What is it for? There's also "Data Mine" feature. Is it for enrichment?
Overall, uploading experience is great. But I don't know how well does it scale.
