Difference — fictional 2025 examples

Method. Reproduced minus expected result, within an explicitly supplied absolute tolerance, using the same exact input/method versions and a separate checker. Retain originals, code, parameters and environment evidence.

Next step. Investigate reproduction difference. Accept reproducible evidence for review, investigate differences, or withhold an unsupported result.

Inputs, example and sources

Keep the same place, observation period, definitions, units and source versions.

Analysis inputs. Earlier/source value [tonnes]; Independently reproduced value [tonnes]; Original measurement unit; Comparison measurement unit; Compared measure and definition; Documented absolute comparison tolerance [tonnes]; Expected input/method version; Reproduced input/method version; Original result creator; Independent reproducer

Other required evidence. Sampling design; assays; model; density; uncertainty; independent checks.

Evidence gaps — fictional 2025 examples

Method. Check each required item and retain its reference. A documented item is not a scientific, legal or institutional approval.

Next step. Complete the evidence. Accept a fit source for a defined use, restrict it, or request metadata/schema correction.

Inputs, example and sources

Keep the same place, observation period, definitions, units and source versions.

Analysis inputs. Map ID; Map ID evidence reference; scale; scale evidence reference; survey date; survey date evidence reference; lithology definitions; lithology definitions evidence reference; owner; owner evidence reference; access rights; access rights evidence reference

Other required evidence. Map ID; scale; survey date; lithology definitions; owner; access rights.

Evidence completeness alone cannot establish suitability, eligibility, safety, permission or method validity.

Proposed checking role. Geologist, mining/environmental specialist and licensing reviewer.

After the action. Resolved interoperability issues and current verified metadata.

5. Documents and images

Your institution has its own document and image library. Use the same library for reports, photos and other evidence.

Geological Survey and Mines Bureau Documents and images prototype screen
Geological Survey and Mines Bureau. Prototype screen. Select the image to enlarge it.

What you can try

  1. Open Documents and images. Check the institution name.
  2. Use All files, Documents or Images to find a file. Open its preview or download the original.
  3. Use a sample file to try Add file. Private is the starting choice. Public needs a source, permission to share and review.
  4. Use Access preview to try the institution reviewer and Public visitor views.

Files added in the prototype stay in this browser. Public sharing is an access preview. Existing public reference links already work online.

What your institution needs to confirm

6. Data structure management

Data structure keeps the existing source tree, records, charts and map. Manage structure adds a place to propose changes to definitions.

Geological Survey and Mines Bureau Data structure management prototype screen
Geological Survey and Mines Bureau. Prototype screen. Select the image to enlarge it.

What you can try

  1. Open Data structure and choose Manage structure.
  2. Use Add base domain for a main information area. Add inside creates a subject area, a nested subject, an entity type or a field under the right parent.
  3. Give the definition a clear name, code and meaning. Reuse an existing definition when the meaning is the same.
  4. For a field, check the data type, unit, required value, limits and missing-value rule. Save a Draft, then try the separate reviewer view.

An entity type means a kind of thing or event, such as a reservoir or an inspection. Drafts stay in this browser. A demo approval does not change real definitions, data, chart links or sharing rights.

7. Users and access

User management shows example profiles for each institution. People and Roles and access let you review the proposed account screens.

Geological Survey and Mines Bureau Users and access prototype screen
Geological Survey and Mines Bureau. Prototype screen. Select the image to enlarge it.

What you can try

  1. Open User management and choose the institution. The rows are examples, not a list of your staff.
  2. Use View access to check a role. An administrator title alone does not give access to Private files.
  3. Try Preview invitation or Preview access change. Check the role, start date, optional end date and reason.
  4. Review the example permissions and tell us which job roles should receive each one.

These are interface previews only. They create no account, send no email and change no access. Use example details in the preview. Institution verification does not grant a real permission.

8. Can you share data regularly?

We currently use public data and published reports where available. Please confirm whether your institution can provide data directly, so we can avoid retyping or reading figures from PDFs.

Do not enter passwords, access keys or private account details.
