Hi Amritbir,
I think the statement “not actively maintained” is, in fact, a little bit more nuanced. FFRead has never been released and maintained as a generally available feature, and doesn’t have any public documentation.
Rather, it was developed by us for one specific customer to support their specific flatfile-based data exchange mechanism when the customer transitioned from AIMMS 2 to AIMMS 3. FFRead supports the multi-table CSV feature as found in the flatfiles in use by this customer. For this specific customer, we still maintain FFRead, and service the occasional support request.
However, although not a generally available feature, some AIMMS support personnel also distributed FFRead to other customers, because, at the time, we didn’t have native CSV support in any other library. For these customers, I consider FFRead an unsupported library, for which we will offer no support.
For regular CSV files (so, not the multi-table CSV format), we currently have two supporting libraries, DataLink in combination with the CSV provider, and the DataExchange library. Of those two, we’re building a broader data exchange vision around the latter, see also https://community.aimms.com/share-your-product-ideas-37/standardizing-data-exchange-with-aimms-722.
