Percolate uses the following technologies and libraries:
Percolate aims to be flexible while using as few unique concepts as possible. Much of this is achieved with the pervasive use of tags.
The database contains a PostgreSQL 'schema' for each LMS tenant which gives complete isolation between tenants.
Tenants are looked up by one or more hostnames (think "domain name": example.com, lms1.example.org, lms2.example.org, etc.).
If you prefer, you can create a single tenant and treat Percolate as a single instance, ignoring the multi-tenancy aspect entirely.
The database stores these basic elements:
enrollment rules (erules)
comments (for discussions)
config (tenant-specific system settings)

Types of content
There are four types of content:
SCORM - the standard e-learning package uploaded to the LMS in a .zip file
Content Builder or just "content" - the native content type in Percolate which is composed of pages containing images, videos, audio, quizzes, file attachments, etc.
Discussions - small forum-like discussion boards
Learning Paths - lists of other content put into specific order, may be nested
People may be grouped and organized by tags.
Percolate LMS Administrators are simply people with the special
$admin system tag.
An initial administrator account is created for each new tenant.
Content is likewise organized by tags.
There are system tags for content such as
$certificate which can affect how the LMS treats the content.
Assignments are made by creating "enrollment rules" which may be one of these four types:
Person to Content
Person Tag to Content
Person to Content Tag
Person Tag to Content Tag
Bascially, an enrollment rule can be as simple as assigning one content item to one person or as complex as assigning an entire lesson plan to a group of people.
Because people in an organization can sometimes be part of overlapping groups, Percolate has a more advanced feature for creating logical combinations of tags called "metatags".
Metatags use boolean operators
OR to combine exactly two other tags (example:
sales AND department-c).
After being created, metatags are automatically appended to any person who matches the rule (anyone who has both the
department-c tags in our example).
When a person launches a content item, a record is created or updated with the launch time, launch count, etc. All content types have the same basic records, even discussions. Other types such as SCORM and those made with the Content Builder can record much more information.
