Assembling Databases By Merging

Now that some species databases have been constructed, it becomes possible to assemble bigger ones by merging some existing databases together A hypothetical diagrammatic example is shown in Figure 9. 3 . 9.3.1 International Legume Database and lNf0RMATi0N Service One of the earliest projects to create a computer database for a large group of organisms was ILDIS (http www. ildis . org), the International Legume Database and Information Service. It was started in the 1980s when the wider...

Basic Problem

The main reason for creating a database is to organize the available information into a number of discrete, labelled fields, which can then be searched to provide the information required by the user (Figure 6 . 3) . Human-readable text is not structured according to logical fields and is seen by the computer as a string of characters, preventing the automation of complex queries . A database, on the other hand, is essentially a collection of separate fields, allowing the accurate specification...

Querying Xmltagged Text

The once concise taxonomic description has been transformed into a much longer, much more unwieldy document by the XML parser, but the important aspect for the automation of digital capture is that that the tags allow complex searches to be carried out of the type - < GENUS confirmed true> < NAME> Gloriana< NAME> < DATE> 1986c< DATE> < PAGE> p. 313< PAGE> < TYPE> *Cryptiana superbia Nelson, 1856, p.413 < TYPE> < SYNONYM> Paradesia SMITH, 1871, p. 54...

ILDIS Legume Web

Because the Alice software that supports the ILDIS database is a single-user DOS program and therefore provides its user with only a local user interface, it is unsuitable for hosting a FIGURE 9.4 Conversion of the ILDIS database to LegumeWeb. The upper user is the ILDIS database editor, who also initiates the conversion process, shown with solid lines . The lower user is an end-user of the LegumeWeb database, whose Web interactions are shown with broken lines Web database. It was necessary to...

Providing Access To Unitlevel Data The Enhsin Prototype

At the heart of the European Natural History Specimen Information Network lies the technical development of a simple XML-based prototype for providing a common access system to specimen databases (Guntsch 2003) . The system was designed to handle distributed and heterogeneous collections' databases . Projects outside Europe of a similar scope include Species Analyst 6 and REMIB 7 . The partnership that constituted the network also examined broader questions of the usage of such information,...

Conservation Of Rattans On Borneo

With an area of 751,000 km2, Borneo is the third largest island in the world, stretching from about 4 S to 7 N . Politically, Borneo is divided among three countries Brunei Darussalam, Indonesia (Kalimantan) and Malaysia (the states of Sabah and Sarawak) (Microsoft 2000 see Figure 10 . 1) . Large tracts of Borneo, particularly the southern and eastern regions, consist of hilly lowlands and swampy plains The central and north-western regions are dominated by mountain ranges with peaks rising to...

Conclusion

Although creating a network of biological collection databases requires, and is receiving, attention from the international community beyond Europe, there are three main reasons why a strong European focus on this project has emerged First, the European Commission is materially supporting the development of natural science collections as an infrastructure Second and closely associated with the first point is the establishment of the European Research Area, which is predicated on the need for...

Assessing Concept Stability

Stability Natural Vegetation

For an analysis of concept stability, we need more data than are contained in traditional checklists with their lists of synonyms although these can also be used for analysis see Geoffroy and Berendsohn 2003 . Instead, we need data sets where concept relationships have been recorded in a comprehensive way i .e. , for every taxon processed rather than in the largely anecdotal way found in traditional treatments In analysing such data sets, we have to be conscious of the fact that the resulting...
