I need to find information about active chemical data sources from 'Government' organizations in 'Japan' on PubChem. Can you tell me the name of one such active data source, how many 'Live Substances' it contributes, and its 'Last Updated' date? Additionally, I'm interested in understanding how PubChem handles 'Legacy Designation' for data sources. Can you explain what a 'Legacy Designation' means for a data source and where I can find more details about it on the PubChem documentation?
Navigate directly to the interactive 'Data Sources' page at 'https://pubchem.ncbi.nlm.nih.gov/source'. Under 'Source Category', select 'Government'. Under 'Source Country', select 'Japan'. Under 'Source Status', select 'Active'. Identify one active 'Government' data source from 'Japan' (e.g., 'Japan Science and Technology Agency (JST)'), its 'Live Substances' count, and 'Last Updated' date from the displayed table. Navigate to the 'Docs' section from the main navigation menu. On the 'Docs' page, locate and click on the 'Data Sources' link. Within the 'Data Sources' documentation, find the section or link related to 'Legacy Designation'. Explain what 'Legacy Designation' means for a data source and state where its details can be found on the documentation page. Synthesize all collected information to answer the task.
The agent successfully navigates directly to the interactive 'Data Sources' page at 'https://pubchem.ncbi.nlm.nih.gov/source'. The agent correctly applies filters for 'Government' under 'Source Category'. The agent correctly applies filters for 'Japan' under 'Source Country'. The agent correctly applies filters for 'Active' under 'Source Status'. The agent identifies 'Japan Science and Technology Agency (JST)' (or another valid source if available after filtering) as an active government data source from Japan. The agent states the correct 'Live Substances' count for 'Japan Science and Technology Agency (JST)' (or the identified source) as '3,275,553'. The agent states the correct 'Last Updated' date for 'Japan Science and Technology Agency (JST)' (or the identified source) as '2025/07/04'. The agent successfully navigates to the 'Docs' section. The agent successfully navigates to the 'Data Sources' documentation page within 'Docs'. The agent correctly explains that PubChem uses a 'legacy' designation to give users the option to filter collections that are not regularly updated. The agent correctly states that the 'legacy' designation applies to project/contributors that appear to no longer be active, as well as to their individual records. The agent provides a comprehensive answer combining all requested details.
