# EDIT WP5: First EDIT Developer Meeting - BGBM Berlin September 6-7, 2007

## Meeting minutes

_Note: areas requiring further discussion are in italics._

## Day 1 - Developer Presentations

The first part of the meeting consisted of 10 Minute Developer Presentations (listed below). Any relevant discussion/decisions or suggestions have also been recorded.

1. **Malte Ebach (BGBM) – BDTracker** 

Please start using the Tracker, we would like to establish this as something that exists well beyond EDIT’s 2011 end date.

2. **Lutz Suhrbier (FUB) - Shibboleth SSO** 

OpenID or Shibboleth debate must take place soon, in light of the substantial consequences for client developers, service providers.

3. **Andreas Kohlbecker (BGBM) - Experts database & Dataportal for WP6** 

4. **Simon Rycroft (NHML) - Community Websites with Scratchpads** 

Scratchpads represent a bottom-up approach, with the philosophy that to have semi-structured data online now is better than nothing – the hope is to “meet in the middle” with EDIT’S top-down approach; 

Markus: aren't Scratchpads better suited to community building, EDIT for real taxonomic work?

5. **Julius Welby (NHML) - Virtual library** 

ViTaL scheduled to go live month 30

Use CDM community store as metadata repository?

6. **Marc Geoffroy (BGBM) - Common Data Model in UML** 

Unfortunately not as easy as hoped to work collaboratively with Enterprise Architect (or more precisely the SQL*Server it runs on top of).

7. **Andreas Müller (BGBM) - Common Data Model java library + sync store** 

_Discussion: Hibernate consequences, how easily can it be hidden? Is CATE’s temporal state solution - "snapshots" of an object at a point in time - the best way to update objects and guarantee their validity?_

8. **Pepe Ciardelli (BGBM) - Taxonomic editor** 

Good example of Eclipse Rich Client Platform used for a biological application: Bioclipse http://bioclipse.net

9. **Dave Taylor (RBGK) - Use cases & workflow modeling outcomes** 

Results of questionnaires on revisionary taxonomy models at http://dev.e-taxonomy.eu/trac/wiki/RevisionaryModels

Gregor: are there areas other than revisionary taxonomy for which the platform will / should be used?

10. **Dilan Latif (SMNS) - ATBI platform w/ field recorder & site database** 

Use CDM community store as central observation repository for an ATBI site?

11. **Magda Zymtoska (MIZPAN) - Geo services**   

12. **Pere Roca (MINCN) - Spatial completeness analysis & Taxonomic data visualisation** 

## Day 2 - Developer Tools

 **The EDIT wiki** 

* http://dev.e-taxonomy.eu/trac/wiki/

* All users have permission to edit all sections - go nuts!

* Note from Malta: we should try to establish as many collaborative activities as possible by the next development meeting in February, because our lack of integrative work was criticized by the Scientific Advisory Committee

 **SVN** 

* All code should be checked in to http://dev.e-taxonomy.eu/svn

* Try to get all source code to date checked in by **September 21** 

 **Trac** 

* Ticket overview at http://dev.e-taxonomy.eu/trac/report

* Tickets don't have due dates, but they are associated with milestones, which do

* MyLyn

  * Trac plugin for Eclipse, comes standard with 3.3

  * Tickets associated with source code files in which appropriate changes were made

  * Eclipse settings: http://dev.e-taxonomy.eu/trac, "XML-RPC"

## Day 2 - Common Data Model

 **EDIT developers' access to the CDM** 

* Unfortunately no access available from outside BGBM-Berlin

* Send proposed changes to CDM mailing list (dev-edit@mnhn.fr)

* Latest Enterprise Architect file (*.eap) available at http://dev.e-taxonomy.eu/trac/wiki/CommonDataModel

 **Platform Independent Model (PIM)** 

* Used to generate model in Java Model using Enterprise Architect's transformation functionality

* The source for the CDM view at http://wp5.e-taxonomy.eu/cdm 

 **eu.etaxonomy.cdm.model.description** 

* For taxa, specimens, observations

* Still largely empty, copied almost directly from SDD

 **eu.etaxonomy.cdm.model.name** 

* Gregor proposed changing **name** to **scientificname** 

* Different subclasses created for different nomenclatural codes, i.e. "!BacterialName", "!ZoologicalName", etc. Initially skeptical of too many class hierarchies / subclasses, but it proved helpful for things like the name subclasses.

* _Discussion: in class "!NonViralName", is "isAtomised" the best way to express whether a full name has been parsed? Alternative naming suggestions in the attribute notes._

 **eu.etaxonomy.cdm.model.publication** 

* Modelled on BibTex, which has wider acceptance, a better reputation, and more software than EndNote

* Native speakers agreed **reference** is more accurate than **publication** 

* _Discussion: publication year properly belongs in **publication** not *name*, even if this requires creating a dummy publication for a nomenclatural reference (similarly, basionyms will require the creation of an incomplete author object for basionym authors)_

 **eu.etaxonomy.cdm.model.location** 

* This package and **eu.etaxonomy.cdm.model.specimen** should be extended for ATBI

* Gregor: change "Region" to "!NamedArea", get rid of "Locality" OR make it a free-text attribute of "!NamedArea"

* Magda: add "accuracy" and "reference system" (a.k.a. "datum") to main class; the latter is necessary because coordinates can vary from system to system

* Markus: how could shape definitions / polygons be stored for regions? Standard shape files? GML /XML?

* Regions also have language implications

* Change "Country" to "!IsoCountry"?

* Pere: distinguish between natural, political, etc. regions

 **Miscellaneous** 

* Abstract class names in Enterprise Architect are in italics

* Logic behind design decisions are written in the notes fields attached to the entity in question – high priority to get these populated!

* _Discussion: for boolean fields, should there be the possibility of a 3rd state, i.e. NULL? DB implications – how does hibernate handle NULLs?_

## Breakout Sessions

### Common Data Model

The first day session focussed on multilingual controlled vocabularies. See wiki:FirstDeveloperMeetingMinutes#Day2-CommonDataModel for outcomes.

### CDM Library

Attendees: 

* Andreas Müller

* Ben Clark

### Geoservices + ATBI

Attendees: 

* Pere Roca

* Magda 

* Markus Döring

### Tax Editor Requirements

Attendees: 

* Pepe Ciardelli

* Dave Taylor

* Eckhard Raab-Straube

The main topic of discussion was how to integrate the use case work done by Dave and his colleague at Kew Soraya Villalba into the design  of the Taxonomic Editor user interface. Dave's work for EDIT Deliverable 5.2.1.1 gathered descriptions of the work processes used by revisionary taxonomists throughout the EU to produced integrated use cases. Soraya's use cases (UseCasePalmMonography) (also detailed in proposals for Palm Web sent a few months ago to Eckhard) - detail the initial publication of a monograph and the attendant peer review process. 

To date, Pepe's work on the UI design has been based largely on duplicating the functionality (EditorRequirements) of the Berlin Model Web Editor, which was built mainly to edit imported checklists; the work done by Kew will help extend the new Editor's functionality to a wider range of users. Known bottlenecks in the Web Editor - such as frequently used functions requiring a maddening number of clicks - will be relevant during UI design. In addition, the group of taxonomists working at BGBM-Berlin has a range of technical sophistication, and the UI development team in Berlin hopes to enlist as many of them as possible for usability tests and the like. Dave will likely join Pepe in the actual coding of the UI.

Dave and Pepe will be at the TDWG conference in Bratislava next week, and will continue the discussion there. 

### Drupal

Attendees: 

* Andreas Kohlbecker

  *	Lutz Suhrbier

  *	Simon Rycroft

  *	Julius Welby

The breakout group discussed on how the development and integration of Community Web Tools (mainly based on Drupal) can be improved and facilitated.

As an outcome to this, a [[DrupalModules|page on Drupal modules]] has been introduced into the developer Wiki by which experiences and EDIT specific modules are to be shared. This page will initially cover all modules used by bdTracker, by the EDIT WP5 Wiki and by the Scratchpads. By this we ensure a better harmonization between development made at the BGBM and at the NHM. 

There has been furthermore a intense discussion on finding the best way to incorporate data exchange between the modules which are used in the Scratchpads and the CDM (Common Data Model) Store. 

Another conversation was on Sibboleth, which has been chosen as authentication framework for the EDIT platform for cyber taxonomy. 

Once the Shibboleth module for Drupal is finished, it will be installed into the Scratchpads to also allow federated login into this CommunityWebtools Compilation.
