TERN EcoPlots

The aim of EcoPlots is to harmonise plot-based ecology data from different sources to enable integrated search and access to data based on different jurisdiction, data sources, feature types, parameters and temporal extent. The EcoPlots is developed based on semantic data integration approach, each of the data sources are mapped to the TERN Plot ontology. Datasets are generally received from custodians in various forms including PostgreSQL database and CSV file format . In data ingestion process, each of the source datasets are mapped to a TERN Plot ontology including identifying and mapping domain feature types, parameters and categorical values to TERN controlled vocabularies, performing data validation routines and resolving taxonomic names. All data are organised in Resource Description Framework (RDF) and stored in a triple store.EcoPlots的核心目标是对来自不同来源的样地生态学数据进行标准化整合，以支持基于不同管辖范围、数据来源、要素类型、参数及时间范围的一体化数据检索与获取。本项目基于语义数据集成方法开发，所有数据源均被映射至TERN样地本体（TERN Plot Ontology）。数据集通常由数据保管方以多种格式提交，包括PostgreSQL数据库与CSV文件格式。在数据摄入流程中，各源数据集均被映射至TERN样地本体，具体包括识别并将领域要素类型、参数及分类值映射至TERN受控词汇表，执行数据验证规程，以及解析分类学名称。所有数据均以资源描述框架（Resource Description Framework）进行组织，并存储于三元组存储库中。

背景与挑战

背景概述

TERN EcoPlots是一个平台，旨在搜索、整合和访问澳大利亚的生态观测数据，包括系统调查和样本数据。它采用语义数据集成方法，将多来源数据映射到统一的本体，并使用标准化词汇进行组织。数据以RDF格式存储，支持用户跨数据集搜索和获取综合性数据包。
