Extracting Asset Hierarchy from PDF P&IDs in Cognite Data Fusion

In a hypothetical scenario where we need to extract asset hierarchy directly from PDF-based P&ID documents, does Cognite provide a built-in library to support this? Or would we need to rely on external libraries like PyMuPDF or pdfplumber for data extraction—or even tools like Pytesseract in cases involving scanned images?Thank you for any guidance on best practices or integrations for this use case!

Hello everyone,I have a problem viewing 3D. It tells me that I don't have any scenes created, but I do have some. I understand that the error message is because I have to configure the location in the scenes. How do I do that? I don't see the option to add the location.

Guidance on Versioning Data Models in Cognite

Hi Cognite Team,I'm curious about the specific rules you follow for versioning views, particularly with the versioning format like "@view(version: 'v4')". I’ve noticed that the last number is the only one that changes, and I wanted to understand the rationale behind this.In my experience, I typically use the X.Y.Z format, where:Major versions indicate significant changes or potential backward-incompatible updates. Minor versions introduce new features or enhancements. Patch versions address bug fixes or minor improvements.While I understand that tools like DVC are more suited for tracking actual data changes, we are focusing on versioning the views and models. Is this approach aligned with your guidelines?If there aren’t any formal rules, that’s perfectly fine; we’re just trying to establish our own conventions and best practices. Versioning is an important aspect for us, and any insights you could share would be greatly appreciated.

OPC-UA extractor - docker settings for periodic reporting of values regardless of change

Hi everyone,I’m facing a challenge with our current setup and would appreciate some guidance from the community.We have an OPC-UA server running on a Siemens IPC Linux machine, which serves the variable values of a Siemens PLC. This OPC-UA server is queried by an OPC-UA client inside a Docker package (Cognite OPCUA Extractor) that sends the data to Cognite Data Fusion (CDF). The data points are then stored in their respective time series within CDF.The issue is that, during periods when the physical quantity doesn’t change (e.g., motor current at zero during weekends), no new data points are sent to CDF. As a result, when the motor starts again, and the current shoots up quickly (for example, up to 2 Amps in 40 ms), this rapid change is not properly reflected in the time series. Because we only scan every 100 ms with the PLC, and since no data was logged during the weekend, it appears in CDF as though the current gradually increased from 0 to 2 Amps over the entire weekend. This is cau

Monitoring and Alerting [Early Adopter]

Possibility to Add More Detailed Data in Email Alerts from Charts

Hi everyone! I’d like to know if there’s a way to edit the information included in email alerts generated by Charts. Currently, the email only shows the tag and states that the limit has been exceeded, but it would be helpful to include the actual value that exceeded the limit, rather than simply noting the exceedance. Is there any way to customize this information in Charts?

Efficient way to learn Cognite

I have been practicing data science, building data pipelines, feature engineering, building machine learning models and deploying them , for past 15 years and I have worked in AWS , Azure and GCP clouds. So what is the fastest way to learn Cognite and start using it ? What are the most important courses and certifications that would help me get going ?

Trying to setup an asset hierarchy with Core Data Model, but am getting some errors

I am trying to setup an asset hierarchy using the Core Data Model as shown in the example:https://docs.cognite.com/cdf/dm/dm_guides/dm_cdm_build_asset_hierarchy/But I am getting some strange errors when I try to implement it. A normal container and view without a refernce to core data model works fines, but when trying to add cdm it fails. I am using the toolkit to deploy the data model.In the “Data management” tab I get this error:{ "title": "", "message": "Cannot read properties of undefined (reading 'listPump')", "errors": []}In the “Query explorer” I get these errors:{ "errors": [ { "message": "The field type 'Cognite3DObject' is not present when resolving type 'Pump' [@-1:-1]", "locations": [], "extensions": { "classification": "ValidationError" } }, { "message": "The field type 'CogniteSourceSystem' is not present when resolving type 'Pump' [@-1:-1]", "locations": [], "extensions": { "classification": "ValidationError"

Data Modeling – Approaches to Defining SPACEs

In a hypothetical scenario where your company has more than 100 sites across different countries, each containing multiple units, it's important to organize data in a way that ensures scalability, flexibility, and ease of maintenance.We have our own perspective on the matter, but we would like to hear from other specialists, especially those experienced in data modeling approaches, like yourself. Example 01: Managing Employee Information Inside CogniteQuestion: Should we separate SPACEs for each site? Example Structure in Cognite Data Fusion:You can structure the SPACEs for your company’s sites and units as follows: Top Level: Country Create a SPACE for each country to organize data regionally.Example: US, BR, IN (for the United States, Brazil, and India). Mid Level: Site For each country, create separate SPACEs for each site within that country.Example: US_COR, BR_SAO, IN_BOM (COR for Corpus Christi, SAO for São Paulo, BOM for Mumbai). Low Level: Unit Inside each site’s SPACE, cre
