title: East Asian Prehistoric Anthropomorphic Jade Object, Specimen 02 (EANJ_FIGURE_02):
High-Resolution Digital Documentation of Morphology, Perforation Structures, Surface Condition, and Observable Modification Traces

description: 1. Core Statement

1.1 This record contains high-resolution original visual data of a jade object in anthropomorphic form (Object ID: EANJ_FIGURE_02).

1.2 This dataset constitutes an individual unit within an ongoing, systematic digital archiving project. It is released as a foundational research data layer, intended to provide high-fidelity visual evidence to support non-interpretive morphological observation, traceological studies, and material-related analytical work.

 

2. Access and Use Conditions

2.1 Access Restrictions

In consideration of data security, academic standards, and controlled usage boundaries, the full-resolution original image files contained in this dataset are designated as restricted access.

2.2 Application Requirements

Access requests must be submitted via the Zenodo platform and should include a brief statement of research purpose and institutional affiliation.

2.3 Use Boundaries

This dataset is limited to academic research, teaching reference, visual documentation, and non-interpretive comparative analysis.Without explicit authorization from the dataset publisher, any form of commercial use, non-academic dissemination, redistribution, or reproduction beyond the scope of academic comparison is strictly prohibited.

 

3. Dataset Composition

3.1 Comprehensive Visual Documentation

The dataset includes full-resolution images capturing the object from frontal, reverse, lateral, and macro perspectives (e.g., perforation structures, surface alteration states, and observable tool-related traces), documenting overall proportions and geometric morphology.

3.2 Measurement Reference Images

Images incorporating metric scale bars are provided for basic dimensional and proportional reference:



Length: 5.2 cm

Width: 2.1 cm

Thickness: 1.2 cm

Weight: 25 g


Note: Due to the complexity of the object’s contours and volumetric structure, the listed dimensions are approximate and should not be regarded as precise measurements.

3.3 Macro Imaging Records

Multi-angle high-magnification macro images are included to document the following directly observable visual features:



Perforation and drilling structures

Surface erosion and depositional conditions

Identifiable shaping or finishing traces

5. Imaging Methodology and Processing

5.1 All images were captured using a full-frame camera paired with a 90 mm macro lens. Original data were recorded in RAW format and subsequently converted to JPEG files for dataset release and presentation. Each image has an approximate resolution of 42 megapixels.

5.2 Photography was conducted under controlled lighting conditions with a neutral background to minimize environmental interference with the material’s visual appearance.

5.3 No physical treatment, cleaning, or surface intervention was applied to the object during the imaging process.

5.4 Where post-processing was applied, it was strictly limited to global exposure and white balance adjustments, with the sole objective of accurately reflecting the object’s material and surface condition.

 

6. Compliance and Due Diligence Statement

6.1 The organization, digitization, and publication of this dataset adhere to fundamental principles of academic data management and research ethics.

6.2 Prior to release, internal compliance and risk assessments were conducted, including evaluation of usage boundaries, potential risks of misinterpretation, and consistency with academic standards.

6.3 This dataset is published solely as a non-interpretive visual record. It does not constitute any academic conclusions regarding function, cultural attribution, chronology, or typological classification, nor does it represent the position of any institution or individual.
