I know this is a late response but I am currently in the same boat. I have learnt the basics but now need a bit more in depth knowledge.
I contacted 65Bit but they directed me towards the user manual but its not the most helpful document in the word!
Hey, I’m teaching EasyCatalog since 2011, but only in spanish. I’ve translated the user manual and work like a consultant and teacher of automated catalog publishing. But… my spoken english is not very good, sorry (I self taught the language during my daily train to and from the University, long time ago). I speak english like a sioux indian of the 70’s westerns films era… but we can try!
I’m late to the conversation on this one, but for those who come across this – The EasyCatalog Quick Start PDF that 65 Bit provides is an excellent starting point and it contains 7 easy to follow tutorials. EasyCatalog and data publishing is not simple – you need to put in the time to study and practice.
If you have the name of the style in your data source, it’s easy. You can apply an style to a text using the mapping styles function, or via the formatting rules style property, or by using HTML notation and specifying the css equivalence with a paragraph style… EasyCatalog is very very powerful and flexible, and has so many options that maybe makes it a bit difficult to fully understand it.
My first recommendation is, please, append a sample of the data source you’re using, the version of InDesign and the version of EasyCatalog you’re using.
