There are a number of ways to query and retrieve information from the database. Below you can query based on labels, which are an effective way to group data and sample metadata based on a particular category. From there, you can filter results based on columns or (soon) dynamically.
Labels are used to organize all the data in the graph database. Here you can filter data based on labels denoting different physical entities, dataset types, habitats, and select sites. For most data-related queries, you probably want to use one of the dataset type labels.
In the query output tables, each row represents a node, and each column (except for the first "node labels" column, which lists all the labels on each node) represents a property. Properties ending in "__" have been mostly standardized throughout the graph database, and are therefore very useful for harmonizing data from different sources.
A full list of label and standardized property definitions can be downloaded here. For a more comprehensive overview of the graph database structure, which may aid in understanding the query output, see the more detailed overview here.
If you select one label, you'll get all the nodes associated with that one label. When running a live query (in development), if you select multiple labels, you'll get nodes that have all of those labels (which may not be many). When retrieving cached queries, which are built on a semi-regular schedule but give instant results, then you can only select one label at a time when running queries. The live querying will remove that restriction, but for now, you can still further refine your results by filtering the output table. For smaller output files, this can be done within the browser as follows:
Choose one of the following labels (scroll down for the full list of options*; color codes are given in the explanatory text):
