2015 NI Minutes of the Workshop: Difference between revisions

{| class="wikitable"

The Energy ADE is structured in separated modules as decided in Stuttgart in May 2014. Each module is developed, documented and updated by a working group with expert participants and two working group coordinators:

*Energy ADE Core: Romain Nouvel and Mostafa El Fouly

In the revision process, these coordinators are in charge of animating the working group with intern online meeting, and centralizing the discussed updates related to their Energy ADE module. Experts can participate parallely to several Working Groups.

CityGML standard is formally defined with a XML schema. The same applied to its ADEs. It allows in particular for the automatic generation of class objects within Java, Python etc. using some dedicated plug-ins (e.g. JavaXB), which is essential during the revision process.

<br/>

In our Energy ADE group, our Technical Committee composed of Olivier Tournaire, Marcel Bruse and Joachim Benner, is in charge of the XML schema development and update. Updates are integrated to the UML model (designed in EnterpriseArchitect) which is converted into a XSD schema (with ShapeChange) compliant with CityGML ADE standard UML. Every revision agreed in the different working groups should be communicated to them, so as to be implemented in the Energy ADE. A central Email address will be created for this purpose.

This GitHub platform centralizes the issues and discussions of all Energy ADE participants between two ADE releases. Issues are related to specific Energy ADE Modules through its "label". They can be created by everybody. Some specific assignee may be given. Once an issue has been resolved after discussion inside a working group, leading to a solution in the XML Schema, it can be closed.

It has been decided to use our wiki page hosted by SIG3D only for external communication, using from now only the public page. Our dissemination activities (paper and conference) will be moved from the community portal to the public page. The GitHub platform, more adapted for our revision process, will replace the development part of the "Community Portal".

<div style="color:#ff0000"><b>ACTION (E. Casper/July15)</b>:Shift dissemination information from restricted page to the public page. Shift the information related with WG work to GitHub. Work on the wiki interface to make it a bit more fancy. Put onto the wiki: the UML diagrams, the contacts, name of working groups (like the GitHub homepage).</div>

#Raise issues within the WGs Meeting / on GitHub.

#Discuss these issues within the WGs and agree on a solution.

<div style="color:#ff0000"><b>ACTION (TC/July15)</b>:Create a Gmail address for contacting TC.</div>

The actual Energy ADE version 0.5 has been released in March 2015, after a 6-month development process. It is compliant with CityGML ADE standard UML modelling and ISO-19xxx. There is presently no documentation about it.

*Latest in 2020, all municipalities have to store and manage geodata, in particular on buildings.

*In Inspire, 34 data themes are related to energy, but the use cases about energy are limited.

*Inspire provides technical Guidelines, UML interchange (XMI), GML standards (XSD), etc.

*It proposes a template for a table listing attributes and used for documentation

The European Project SunShine attempts to develop an automatic way to determine building efficiency and (pre)certify buildings based on 3D city model (so-called ecomap). Nevertheless, we must be careful about the validity of the energy labels results due to uncertainty into the input data and the calculation method (missing refurbishment measures for instance).

3 small group have worked in parallel on the class diagram of the version 0.5 of the Energy ADE, discussing with the WG coordinators and identifying some further development requirements.

Overview of CitySim, an Urban Energy Platform developed in EPFL. Its data model is organised in 4 different modules: Building geometry, Building envelope, Thermal zone, Energy systems.

<br/>

|-

Explanation of data structure of SimStadt and how it is planned to integrate the Energy ADE Schema (XSD file) within it, using JavaXB and some binding functions. For further information, contact Marcel Bruse from the HFT Stuttgart which is realising this technical task.

Different proposed approaches for Metadata integration

<br/>

|-

To concretly integrate the ADE into their Database (software novaFACTORY), MOSS transforms the ADE into Generic Attributes and store them into an external database.

-> Possible problems:

*Different locations

*Problem with different version of ADEs but possible way to automatically provide tables.

-> Alternative solution from KIT & Claus Nagel (VirtualCitySystem) :Copy the schema into a directory and work on it. VCS deals with the dataset. Extend the table.

<br/>

Possible solutions are under construction at the TU München: Import/exporter for the timeline to be ready with CityDB (Gia Yao Zihang in TU Munich). Information should be provided in a close future (cf. Mostafa or Prof. Kolbe)

We have defined Time Series for the Energy ADE Module “Energy and Systems”. We know that the development team of CityGML 3.0 aims at integrating this concept in the new CityGML release.
