I'm pretty new to wordpress and would appreciate some of your opinions.
I'm creating a site for a school project that will allow readers to search for information about research articles. Basically I want to display:
Research article excerpt (one or two sentences)
Topic (Microbiology, Endocrinology, etc.)
Keywords (heart, cancer, etc.)
I was going to use posts for the excerpt (although I'm open to custom posts if you think those are better for some reason - I don't plan to use this as a blog). I'm not sure how to organize the remaining information. For eg, do I place the author names as a children of category Author? Should I use taxonomy? Or would custom fields be a better option? Topics as custom fields? Keywords as tags or custom fields? There may be hundreds of authors with multiple papers written by them and several topics. I've heard wordpress slows down if you have too many categories so I want to make sure to do this right. I also want to know what is best for SEO. When somebody searches the topic, the keyword or the author, I'd like it to come up so for that reason also I want to put these things in the right place.
