Back when I first started this site, I was doing some work with biographies as sources of historical information and other information. I eventually moved away from that approach, although signs of it still remain on the site. However, biographical information in the latest version still drives a lot of the development.
With the current approach, science and nature are only mentioned for most individuals.
Areas of the human body and psychology are perhaps more applicable, but not sufficiently well developed themselves. I have about two dozen individuals I am working with, and the number will continue to increase. I'd like to work with contemporaries and associates of these individuals, but I need information from history and peoples in order to do this, as well as more than just a few individuals.
Anthropology is not very useful yet, but I have been working in human geography and have major areas of Europe, Asia including Southwest Asia, and North America connected to biography, so that I can at least place individuals in the right general area.
Culture will be very important, especially conceptual culture which will include literature and source material about people's lives. Other areas of culture can also be used once they are better developed.
Institutions are not yet developed enough to be very useful.
Social changes and movements aren't yet developed enough to be able to connect them to biography, and the direct connections between a list of individuals and a list of major cities are rather sparse. I can categorize individuals by the major peoples they belonged to, which is somewhat useful.
The easiest grouping is to identify individuals by when they lived. Many of the most significant ones lived in classical and medieval times, which is not where mt principal focus in history is. Instead, I have been looking at the 19th and 20th centuries. These will be more useful in examining biographies when I have more individuals from later times.
