Geohazards, e.g. floods and landslides, are increasingly resulting in loss of life and economic damage. Process models can help the understanding of the frequency and occurrence of these hazards, reducing their impact. However, models require significant resources to develop and, ideally, should be made widely available. Further, integrated modelling demands that process models are discoverable, available and, ultimately, linkable. Metadata standards are defined for data, but the equivalent for process models are not yet available as an international standard or even as accepted best practice. Requirements have been gathered for model metadata using a questionnaire and a metadata schema has been developed. The resulting schema split model code (software) and model instance (application) given that model codes are used multiple times. International data metadata standards, e.g. ISO19115, have been used for the core of the standard. The schema has been implemented via the PURE portal (www.pureportal.org) which makes models available and forms the basis of an international standard for model metadata.

洪水和山体滑坡等地质灾害日益造成生命损失和经济损失。流程模型可以帮助您了解这些危险的发生频率和发生情况，从而减少其影响。但是，模型需要大量资源才能开发，理想情况下，应使其广泛可用。此外，集成建模要求过程模型是可发现的，可用的，并且最终是可链接的。元数据标准是为数据定义的，但过程模型的等效标准尚不能作为国际标准甚至公认的最佳实践来获得。已经使用调查表收集了模型元数据的需求，并且已经开发了元数据模式。在多次使用模型代码的情况下，生成的模式拆分了模型代码（软件）和模型实例（应用程序）。国际数据元数据标准（例如ISO19115）已用作该标准的核心。该模式已通过PURE门户网站（www.pureportal.org）实施，该门户使模型可用并构成了模型元数据国际标准的基础。
