There is a huge amount of data on the co-occurrence of plants in the world. The ability to combine such local or regional data and to exchange data between datasets is highly desirable but most of the plot databases have their own vocabularies, definitions of fields and ‘idiosyncratic structures’. The approach of combining such data in large, centralized data-bases is currently developing well. In addition, however, it would be very desirable if data could be exchanged directly and as loss-free as possible with little effort.The fact that there is no generally accepted standard format for loss-free exchange leads to an extremely high expenditure for data conversions. This is not to say that there are no exchange formats but formats such as the one used for import into the Turboveg software are aimed at a specific target data structure and at standardisation rather than a loss-free exchange. For this reason, there has already been an attempt to develop a new open standard to exchange vegetation-plot data (Veg-X). One of the impediments to the adoption of Veg-X by the scientific community has been its complexity, which is required to accommodate the wide variety of ways vegetation plot data are collected and stored. To ensure that the Veg-X standard serves its purpose, the proposed project aims to facilitate its use.The approach is two-fold. One element is the further development of an R-package for the easy import and export of existing plot data into the Veg-X format. This includes the development of an R Shiny app which allows the functions of the package to be used independently of an R-installation. The second part of the project consists of the implementation of a Veg-X export function for Vegapp, an Android app for vegetation records. This will allow to produce Veg-X data in the field. Both, the R shiny app and Vegapp will facilitate the transformation of data in the Veg-X standard for users who are unfamiliar with R. The web-based application and the data collection tool with Veg-X export will contribute substantially to the exchange, harmonization and reuse of vegetation plot data and should thus advance the study of vegetation.

世界上有大量关于植物共生的数据，非常需要结合此类本地或区域数据并在数据集之间交换数据的能力，但大多数绘图数据库都有自己的词汇表和字段定义。然而，将这些数据组合到大型集中式数据库中的方法目前正在蓬勃发展，如果数据能够直接且尽可能无损地交换，那将是非常可取的。事实上，没有普遍接受的无损交换标准格式导致数据转换的费用​​极高。这并不是说没有交换格式，而是说没有诸如用于导入 Turboveg 的格式。软件的目标是特定的目标数据结构和标准化，而不是无损交换。因此，已经尝试开发一种新的开放标准来交换植被图数据（Veg-X）。通过的障碍科学界认为 Veg-X 很复杂，需要适应各种植被样地数据的收集和存储方式。为了确保 Veg-X 标准达到其目的，拟议项目旨在促进其使用。该方法有两个方面：一个要素是进一步开发 R 软件包，以便将现有绘图数据轻松导入和导出为 Veg-X 格式，其中包括开发 R Shiny 应用程序，该应用程序允许以下功能。独立于 R 安装使用的包。该项目的第二部分包括为 Vegapp（一款用于植被记录的 Android 应用程序）实施 Veg-X 导出功能，这将有助于在现场生成 Veg-X 数据。为不熟悉 R 的用户提供 Veg-X 标准中的数据转换。基于 Web 的应用程序和具有 Veg-X 导出功能的数据收集工具将大大有助于植被样地数据的交换、协调和重用，因此应该推进植被研究。
