Abstract: Conceptualization of information allows improved visualization and manipulation of large amounts of data. Especially in digitization of cultural heritage, and when aiming at presenting more than one monuments, abstraction of information becomes the key solution. Our proposed application aims to present the main archaeological monuments of Crete through a conceptual 3D model. It allows the user to navigate among all the main monuments and approach them gradually in different levels of detail. Furthermore, the ability to switch between the seven historical periods offers a comparative study of their evolution in time. By providing the minimum needed information at each level of abstraction, “level of detail”, we can create an online platform, light and easy to use.
The platform is comprised of the main, central space, where the 3D models are presented, and two scrollable sidebars, one horizontal and one vertical. The horizontal one controls time, and allows the user to switch between the seven historical periods and the vertical one controls the level of detail, allowing the user to switch between more or less abstract modes. At the same time, the user has the ability to navigate in real time in the main space around the models, using pan, zoom in/out, rotate, etc. Only when the user reaches the fifth Level of Detail, that of a single monument, he/she has access to all the available related information, such as photographs, videos, maps, drawings, text, links, etc. Use of keywords allows a cross-reference function independent of the 3D models.
The primary contribution of the proposed platform is the ability to capture time in a comparative format. Some of the issues we are currently working on are:

  •  Subjectivity due to abstraction.
  •  Use of multiple semantic links.
  •  Interoperability / expansion
  •  Conceptual Modeling Language (ConML).
