title: East Asian Prehistoric Anthropomorphic Jade Object, Specimen 09 (EANJ_FIGURE_09):
High-Resolution Digital Documentation of Morphology, Perforation Structures, Surface Condition, and Observable Modification Traces

description: 1. Core Statement

1.1This record contains high-resolution original visual data of a jade object with an anthropomorphic form (Object ID: EANJ_FIGURE_09).

1.2This dataset constitutes a component unit within an ongoing systematic digital archiving project. It is released as foundational research data, intended to provide high-fidelity visual evidence to support non-interpretive morphological observation, traceological research, and material-related analytical work. No interpretive claims are implied.

 

2. Access and Use Conditions

2.1 Access RestrictionsFor reasons of data security, academic standards, and controlled use boundaries, the full-resolution original image files included in this dataset are subject to restricted access.

2.2 Application RequirementsAccess requests must be submitted via the Zenodo platform and should include a brief description of the research purpose and institutional affiliation.

2.3 Use LimitationsThis dataset is intended solely for academic research, teaching reference, visual documentation, and non-interpretive comparative analysis.Any commercial use, non-academic dissemination, redistribution, or reproduction beyond the scope of academic comparison is strictly prohibited without explicit authorization from the dataset publisher.

 

3. Dataset Composition

3.1 Overall Image DocumentationThe dataset includes full-resolution images capturing the front, reverse, and profile views, as well as localized macro images of specific features (such as perforation structures, surface erosion conditions, and visually observable modification-related traces).These images document the object’s overall proportional relationships and geometric outline structure.

3.2 Metric Reference ImagesImages incorporating a metric scale are provided for basic dimensional and proportional reference:



Length: 9.3 cm

Width: 3.7 cm

Thickness: 2.1 cm

Weight: 153 g


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

3.3 Macro Image DocumentationMulti-angle high-magnification macro images are included to record the following directly observable visual features:



Perforation and aperture structures

Surface erosion and depositional conditions

Visually identifiable modification or adjustment traces


All observations are limited to the visual domain.

5. Imaging Methods and Processing

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

5.2Image acquisition was conducted under controlled lighting conditions with a neutral background to minimize environmental influence on the visual appearance of the material.

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

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

 

6. Compliance and Due Diligence Statement

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

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

6.3This dataset is released as a non-interpretive original visual record. It does not constitute, imply, or support any conclusions regarding the object’s function, cultural attribution, chronological placement, or typological classification, nor does it represent the position or viewpoint of any institution or individual.
