EANJ_02: High-Resolution Visual Data Record of a Jade Object

1. Dataset Identification This dataset contains a high-resolution visual record of a single jade object (Specimen ID: EANJ_02).The dataset constitutes a standardized digital imaging archive intended to support non-interpretive visual observation, morphological comparison, and image-based reference within academic contexts. 2. Object Record Object type: Jade object (single specimen) Statement of Scope:The morphological designation used here refers exclusively to the overall external features directly observable in the images and serves as a baseline term for image indexing and visual comparison. 3. Imaging Dataset Structure 3.1 Image Categories This dataset includes the following three categories of images: Multi-angle overall views Macro images of surface features and localized structures Reference image including a scale bar 3.2 File Inventory Overall views EANJ_02_OVERALL_A EANJ_02_OVERALL_B EANJ_02_OVERALL_C Macro views EANJ_02_MACRO_A EANJ_02_MACRO_B EANJ_02_MACRO_C EANJ_02_MACRO_D Scale reference image EANJ_02_SCALE 4. Measurement Data Approximate reference values (non-precision measurements): Length: 2.9 cm Width: 2.9 cm Thickness: 1.3 cm Weight: 22 g 5. Imaging Protocol 5.1 Equipment Configuration Full-frame digital camera 90 mm macro lens 5.2 Data Acquisition Captured in RAW format Converted to JPEG for publication and archiving 5.3 Shooting Conditions Controlled lighting environment Neutral background Non-contact, non-invasive imaging 5.4 Post-Processing Statement No physical cleaning, restoration, or surface intervention was performed Post-processing was limited to global exposure and white balance adjustment No localized retouching, structural enhancement, or detail amplification was applied 6. Data Integrity Statement This dataset represents a static visual record captured at a specific point in time.Its intended use is limited to: Non-invasive visual observation Image comparison and morphological reference Supplementary visual material for academic research This dataset contains no interpretive, attributive, or inferential information. 7. Access Classification High-resolution image content in this dataset is released under Restricted Access.Access requests must be submitted via the Zenodo platform and should briefly state: The intended research or teaching purpose Relevant academic or institutional affiliation (if applicable) 8. Usage & Licensing Permitted uses: Academic research Teaching purposes Visual and comparative analysis based on observable features Other uses:Any additional uses—including commercial applications, data redistribution, or dissemination in non-academic contexts—require prior authorization.Access and authorization decisions will be made by the data publisher based on research relevance, intended use, and consistency with the dataset’s non-interpretive research scope.
