Support the National Vegetation Classification. Provide a comprehensive facility to store the most commonly collected vegetation plot data attributes.Provide the user with a large number of user-defined attributes to store not-so-commonly collected data.Integrate plots with the dynamic plant taxonomy and vegetation community data.
Design meeting September 2000, NCEAS
Plots Database Design Goals
Vegetation Community: Vegetationcommunity assignment. Notice the linkinto the 'concept-based' vegetationcommunity database. Queries issuedbased on a vegetation communityattribute may be used to select all theplots interpreted as that community type.

Plant Taxonomic Observation(s):Plant abundance/coveragedata may be stored for any or all ofthe strata comprising a plot. Uniquely,we have designed the ability forinterpretations of taxonomic elementsto be made and stored in the databasesubsequent to the upload of a plot.Notice the taxonomic elementinterpretation is linked directly to the'concept-based' plant taxonomydatabase.
Plot Observation(s): Environmental andconditional data that have the potentialto change between sampling events. Mayinclude: Soil composition, Observationdetails (dates, contributors, etc.)...

Taxonomy Module
•Smithsonian meeting: Peet-Taswell model vs Berendsohn model
•FGDC Biological Nomenclature Working Group•Update on ABI & HDMS•Prospects for implementation•The difficult choice
Logical separation of a "taxonomic name" with the "taxonomic concept", so that taxonomic data can be stored at the most 'atomic' level without ambiguity
The ability to incorporate multiple organizations' 'views' of how a taxonomic name is applied to a taxonomic concept
The ability to link a taxonomic name used in the Plots database with a 'name - concept' pair in the taxonomic
database.
*Although one can store vegetation community data in the same database table-structure as the plant taxonomy database, we have implemented two separate table structures and have created two separate data sets.
Taxonomy Database Design Goals
Taxon Usage:The usage of a taxon is anapplication of a 'Taxon Nam e'with a 'Taxon Concept'. Thisusage m ay vary depending on theorganization populating the database
Taxon Correlation
Taxon Usage
Taxon Nam e
Taxon Concept
Taxon Lineage
Taxon Citation
Taxon Nam e:The nam e used todescribe a taxonom icelem ent.
Taxon Citation:A reference to literature describ inga specific taxonom ic elem ent.
Taxon Concept:The concept is the over-arching 'defin ition 'of what the taxon elem ent is . In thedatabase, a key associated with eachunique concept is stored in th is entity.
Taxon Lineage:The lineage entitystores inform ationrelated to howconcepts 'lum p'or 'split'.
Taxon Correlation:The correlation entitystores inform ationrelated to howconcepts 'overlap '.

Representative tools reflect the desire to have the following features:
High performanceRobustOpen architecturePlatform neutralScaleable
Development Choices
Java -- Write once, Cross platform – Linux, Windows, MacOS*Java Servlet -- Dynamic, database-driven,
web contentJDBC -- Connect to any database - Oracle, PostgreSql, SQL Server backendSwing -- Classy interface toolsBeans -- Reusable components
Features - JAVA
* Not tested yet :-)
XML: is the format for structured data on the Web.
Simple and flexible data conversions, using XSLT
Straightforward to write generic tools which export parts of a relational database as XML encoded data, or even to write generic code that serializes Java (or other) objects as XML data structures.
Examples later…

Carya ovata(Miller)K. Koch
Carya carolinae-sept.(Ashe) Engler & Graebner
Carya ovata(Miller)K. Kochsec. Gleason 1952
sec. Radford et al. 1968
Splitting one species into two illustrates the ambiguity often
associated with scientific names. If you encounter the name
“Carya ovata (Miller) K. Koch” in a database, you cannot
be sure which of two meanings applies.

General Data Management Practices general formats weird formats unusable formats
modeled the software after the way that peoplecollect plots data -- at least that is what I thought
At times tortuous path to the database in terms of reformating
class indicies (these are rectified at the plots loading software step)
