Lineage is a free and open source Plone product that makes it easy to manage subsites. It works by enabling regular subfolders of a Plone site to appear as autonomous Plone sites to the everyday user.
I will explain the benefits of using Lineage:
- Decreased infrastructure costs
- Increased site performances
- Built-in content syndication
- Consolidated search across all child sites
- Cost-efficient maintenance and upgrades
