Galaxy database - Need help to retrieve a attribute's configured datatype

Question

Hi experts, 
 I'm currently working on a sql script to generate a importable config file for the OI MQTT Publisher. The goal is to feed the script with a list of tags (ObjectName.Attribute), and the output will be a json formatted string that can be imported as a file in the MQTT publisher. 
 The script is 90% completed, but now I'm stuck. The config file must contain information on the tags datatype and I cant find a way to retrieve this from the galaxy database. 
 If anyone can help I would appreciate it!

Hi Kristian, This might be a challenge, I believe created attributes are not represented in the database, at least not in a obvious way. 
 Configuring an attribute with extensions such as IO extension will create some entries, but mostly related to the IO extension it self. 
 I would go for GRAccess to extract configuration-data from a Galaxy.
