Genealogy
Collaboration

Most genealogy software programs can export information about persons and their relationships in a standardized format called a GEDCOM. In that format, it can be shared with other genealogists, added to databases, or converted into family web sites. Social networking service (SNS) websites allow genealogists to share data and build their family trees online. Members can upload their family trees and contact other family historians to fill in gaps in their research. In addition to the (SNS) websites, there are other resources that encourage genealogists to connect and share information, such as rootsweb.ancestry.com and rsl.rootsweb.ancestry.com.
