A typical object that has been reviewed with the Schema-Tec method: The chronograph Peyer-Favarger n°19163, a clock of coincidence used e.g. for the Quervain-Piccard seismograph, located in the basement of the Hirsch pavillon of Neuchâtel Observatory.
Client:
Haute Ecole Neuchâtel for Conservation and Restauration (HE-Arc). Project in cooperation with Zurich University of Arts (ZHdK) and University of Applied Sciences and Arts Northwestern Switzerland (FHNW) in Brugg.

Baseline:
The HE-Arc is the Swiss center for the conservation and restauration of the rich Swiss heritage of technical objects, such as motors, instruments, clocks etc., to mention a few. These objects are called STH objects*. Prof. Degriny created a method to document and describe such artefacts in a non-invasive way. Following the steps of Schema-Tec, no dismantling of an object is needed to go through the procedure. At the end, scientists or conservators might give an answer how to conserve the object and/or if the object can be in use ever again.
Technology:
Web-based tool, PHP
Languages:
English and French
Task:
This project was a service of ZHdK and FNHW to HE-Arc.
Approach:
Project managers were Prof. Degriny for the content and the students of Brugg for the database.
Responsibility:
The project was divided into several work packages (WP). I was involved in 3 of 5 WP. My tasks as person in charge of ZHdK were:
Recommendations for design software
Suggestions for the data storage
Concept of the database following the steps of Schema-Tec
Mentoring the students in Brugg and the assistance in Neuchâtel
Create the visual guidelines for the technical drawings
Design and layout the guidelines and description of the Schema-Tec procedure
Managing autonomously a part of the budget for this tasks
State:
End of 2014 until summer 2017
*Scientific objects and instruments, Technical objects, Horological objects
In the beginning Schema-Tec was planned as a data storage instrument. The problem was the vast kind of sources, document formats etc. created by the students to review their objects.
Functional diagram of schema-tec.ch: Instead of a simple storage I suggested a database with CMS and a widget I named «Schema-Tec manager». The manager follows the 8 steps of Schema-Tec.
