This is a dump file of the NaKnowBase - an SQL based relational database containing curated data from EPA's Office of Research and Development related to the environmental effects of engineered nanomaterials. This dataset is associated with the following publication: Boyes, W., B. Beach, L. Thornton, P. Harten, H. Mortensen, and G. Chan. An EPA database on the effects of engineered nanomaterials - NaKnowBase (from the US EPA Office of Research and Development). Scientific Data. Springer Nature Group, New York, NY, 9(12): 1, (2022).

This dataset is associated with the manuscript "Translating nanoEHS data using EPA NaKnowBase and the Resource Description Framework" mortensen h, Williams A, Beach B, Slaughter W, Senn J and Boyes W submitted 8/3/2023 to F1000:Nanotoxicology. The dataset includes and RDF mapping of EPA NaKnowBase (NKB), the OntoSearcher code used to produce the file NKB RDF, as well as training materials and example files for the user. Portions of this dataset are inaccessible because: this data includes partner data and old code that has been modified since 2021. They can be accessed through the following means: OntoSearcher_Training_Materials.zip. Format: The file entitled "OntoSearcher_Training_Materials.zip" includes updated materials as of 07/11/23. These files include the Ontosearcher tool materials, sample NKB dataset and corresponding training documentation on how to run the tool with the sample dataset, and apply to the users own data. This directory also includes the current RDF mapping of the NKB (NKB_RDF_V3.ttl).

Product CSS.3.2.2 includes three inter-related components, the delivery of which completes this product. This product represents updates to the NaKnowBase database, which has been cleared under STICS Public accessibility for NaKnowBase ORD-043098. The first component is a tool to automate formatting of ENM data into the standard and universally accepted ISO-TAB Nano format. We have written this code to both WRITE (export) NKB data in ISO-TAB Nano format, as well as READ (input) external data already in the ISO-TAB Nano format for potential inclusion into NKB. The code and corresponding documentation for this tool are made available to the public via the EPA Office of Research and Development at: https://gaftp.epa.gov/EPADataCommons/ORD/NaKnowBase/. The second component is an application, entitled “OntoSearcher”, that automates ontological term mapping for a given ENM dataset. We have developed this code to read in external partner ENM data, and map those data to ontological terms with reported diagnostics on speed and accuracy. This is the first step in the development of a common language for ENMs, aims to minimize necessary human curation time and is critical to EPA efforts to integrate across Federal ENM datasets in a FAIR (Findable, Accessible, Interoperable, Accessible) way. The code and corresponding documentation for this application are made available to the public via the EPA Office of Research and Development at: https://gaftp.epa.gov/EPADataCommons/ORD/NaKnowBase/. The third component is the integration of NaKnowBase ENM data with the EPA Chemistry Dashboard. Currently, we have 373 chemical structure mapped on the Dashboard at https://comptox.epa.gov/dashboard/chemical_lists/NAKNOWBASE. This collaborative, intra-Agency effort between CCTE and CPHEA continues as we update NKB ENMs, establish web-services to update NKB-Dashboard integration with the NKB application, build on our EPA standard nomenclature for ENMs (Beach et al.(2021)), and continue our semantic mapping efforts with Federal and International collaborators.
