XEO Primer

Welcome to XEO Primer, the introduction and documentation to the XEO Framework.

Introduction

XEO is an Agile Development framework aimed to ease/speed the creation of web-based management applications by modelling real-world entities (and their behavior) as Object Models, which can then be used to generate web pages for listing, editing and searching instances of those object models.

An example application - XEO Library

In this chapter we describe our very first application, to show XEO's capabilities resolving real-world issues, by describing a management application for a library ( read more).

XEO Studio Introduction

In this chapter you'll learn how to create a new XEO Project using the XEO Studio plugin, and also to deploy a XEO Project ( read more).

Object Modeling - XEO Library

In this chapter we'll model the entities described in the sample application chapter, as XEO Object Models. This chapter will be divided in two parts. The first part consists of modelling a simple entity (Author) and showing how to quickly set up viewers for that Object Model and the second part where the remaining entities will be transformed to Object Models. Links to both sections bellow.
