Hi Team,We are currently exploring migration of our existing content to use Flexible Data Modeling in CDF, and we are facing some challenges while configuring the OPC UA Extractor.At the moment, we are still pointing the extractor to the traditional Asset-Centric Time Series (dataset-based approach) and then transforming the data into our Data Model types afterward. However, we would like to ingest data directly into a view that implements the CogniteTimeSeries type.We would appreciate your guidance on the following: Do you have any example .yml configuration for the OPC UA Extractor that ingests data directly into a view implementing CogniteTimeSeries? Are there any best practices or recommended approaches for this setup? Is the following documentation the correct reference for this use case?https://docs.cognite.com/cdf/integration/guides/extraction/configuration/opcua#data-models Additionally, we are also evaluating OPC Events ingestion: Should OPC Events be modeled using Cognite
When calculating daily totals or averages using the Resample function, the calculation seems to be performed based on the 00:00 – 24:00 UTC timeframe. I would like the system to account for time zone differences so that the totals or averages are calculated based on the 00:00 – 24:00 period in Japan Standard Time (UTC+9).
Do we have a feature in the roadmap to allow for showing annotation to annotation lines (manually added in blue) vs. today just having annotations to file? (I realize there are some DM limitations) See below. The doc to doc annotations (data) and visualization (screenshots) are currently going from a bounding box around the text in the arrow (source doc) to the document (target doc). The line target destination is the center of the document.We have the reverse connection from the bounding box to the center of the doc.What we need is a connection between the bounding box around the text in one document to the corresponding bounding box in the other document.Example: on the left attachment,The left document L12... 74A-1296 annotation goes to the document 1296 on the right. But it attaches to the center of the doc.And R11 ... -74A-1295 on the right connect to the document 1295, connects to the center of the doc.These 2 connections are in orange.The requirement is to have only one connec
I would like to suggest upgrading the Large Language Model (LLM) used by Canvas AI.Currently, the model appears to struggle with understanding technical documents and often provides incomplete or inaccurate answers to relatively straightforward questions. It also has limited ability to interpret visual content such as graphs, charts, and engineering plots, which are common in technical documentation.An improved LLM with stronger reasoning and multimodal capabilities would significantly enhance the user experience by enabling it to:Provide more accurate and context-aware answers. Better understand engineering and technical terminology. Interpret graphs, charts, tables, and other visual elements within documents. Generate more comprehensive and reliable document summaries. Handle complex documents while maintaining context across multiple pages.These improvements would make Canvas AI much more valuable for users working with engineering reports, operational documents, and technical studi
If you use Data Modelling (DM), you either have faced this issue already, or you will very soon.A DM is versioned, which is a very important feature to avoid breaking existing solutions. However, since there is a limit to the number of Views and versions you are allowed to have in a CDF project, you need to deprecate old versions at some point (in particular in periods with heavy DM development).Currently it is not possible to extract from the logs which View and which version are in use. This is a fundamental problem that needs to be solved, but we will not discuss that here.CDF offers three UI features that consume the DM instances of a specified version: Atlas AI agents, Canvas and Charts. It seems they, at the time of the data being added, they use either the latest version of the data model, or the version specified in the location filter (someone in Cognite can confirm this). It means that an evolving Canvas can potentially have instances linked to different versions inside the
As a CDF Platform Administrator,I want the ability to configure the PI Extractor to include ptsecurity and datasecurity attributes in the extracted metadata,So that I can use these source-level access control lists (ACLs) to automate and enforce data access security for groups of users in Cognite Data Fusion. Configuration OptionsGIVEN a standard PI Extractor installation,WHEN looking at the extractor configuration file (e.g., config.yml),THEN there must be a new, optional configuration parameter (e.g., include-internal-security-metadata: true/false or an override setting).GIVEN the configuration parameter is omitted or set to false,WHEN the extractor runs,THEN it must continue to exclude ptsecurity and datasecurity metadata as it currently does (default secure behavior). Extraction BehaviorGIVEN the configuration parameter is set to true,WHEN the extractor performs discovery and extracts Time Series metadata from PI,THEN the ptsecurity and datasecurity attributes must be successfull
Is it possible to remove a Flow App from a Cognite cluster after it has already been deployed?
The comment feature in Canvas is really great and we are planning to use it for our shift handovers. We plan to add multiple comments but having to click the comment icon every time to read the content is quite tedious. Since we want the comments to be immediately visible as soon as we open Canvas, we would love to have a feature, like ”pin” comment content.
Today Canvas cannot show the information stored in a JSONObject. This is unfortunate since method specific information for more general output objects will be stored in the JSONObject to avoid overcrowding the output object. One example is anomaly detection. There will be a large number of different analytics methods detecting anomalies,, each with its own method specific information not relevant for other analysis, but all writing to a common Anomaly View. As long as the analysis specific information will not be used for search and filtering, it will be stored on the JSONObject
I have a timeseries chart in my Flow dashboard. When I select a time range (and press Apply), I see no change to the time range in the chart
I have Canvas’ with View revisions that has been deleted. If I delete the “object” directly in the Canvas, it works well. However, if I delete the Canvas directly without first deleting the objects, I get stranded nodes (FdmInstanceContainerReference nodes). If I delete a Canvas with object linking to existing View revisions, it works well.Would be nice if this was fixed since getting Canvas’ with outdated revisions is relatively common in a period with heavy data model development (revisions are constantly bumping, and we need to clean old revisions to stay below the view/revision limit). Now we are forces to run cleanup scripts on stranded canvas nodes on a regular basis
The proposal is to get in the Search overview, the location of the contextualized tag in the 3D CAD structure. Such feature will help the user from where the 3D CAD contextualization is coming from in teh 3D CAD structure.Rigth now we do not have this feature, and this should allow us to potentially correct, add, remove some pieces of the 3D CAD structure contextualizationSee the attached illustration...
The layers on a PDF are not currently clickable within CDF. I have an example of a file that was loaded as a PDF with certain layers turned off. When we put this PDF in a canvas and then downloaded the canvas, all the layers were turned on, making it difficult to read. It appears Cognite turned on all internal PDF layers when creating the download.Ask: A - Let’s leave the layer state as is when downloading from a CanvasB - Don't embed the layers and leave them exposed in the resulting PDFC - Have layers viewable in Search PreviewD - (Future) Expose the internal layers in Canvas/preview
Problem Statement: Currently, there is no great way to print comments in industrial canvas (If there is not aware of a good way). Potential Solution Option(s):Anchored to DocumentComment Selection box in the download list (similar to multiple pages) that would allow comments to be turned on that would be anchored to the document based where the user placed it. Comment Pane on right side that shows comments for that page. (Similar to microsoft suite review pane)Separate Comment PageComment Page independent similar to the cover page that could be checked or un-checked that would display on a separate page that would be part of the download. Downside is the comments may not make sense if there are not associated with the drawing.
Example: The filter shows options in English, while in the list view they are displayed in Norwegian. For example, the filter shows “Ready”, whereas in the view it shows “Klar”.
Documents that are most important for the technician should be listed first, e.g. P&IDs (XB).

hi, I am taking up the course for data modelling and facing some issues for transformation.Have created an asset named Dutta2026 and while running transformation I receive the error below. Can somebody help me troubleshoot it please? I think it is some kind of access block. [ASSETS] Request with id a8ff7523-7c66-9300-82e5-37961456d56d to https://api.cognitedata.com/api/v1/projects/cdf-fundamentals/assets failed with status 403: Resource not found. This may also be due to insufficient access rights.
Due to the limit on the number or Views/revisions, we need to deprecate and delete old revisions on a regular basis (in periods with heavy data model development). For Atlas agents and Canvas’ we can find the View versions via the API, allowing us to identify users depending on models that are deprecated. However, with Charts I cannot find any way of programmatically finding this.Is there a hidden API somewhere that allows me to inspect what the different Charts are relying on? If not,. this is an important functionality for governance of data models and needs to be added.
I used the Atlas AI agent (default) to locate two timeseries, and then clicked on the “add to dashboard” button. The chart got added, and the title indicates both are added, but the chart only has a single visible line. If I move the mouse pointer down, it snaps to another value (notice the location of the blue point), but not sure if this is the other timeseries or if it is a spike from the raw data that is not shown due to downsampling on the chart. Also, the time range selection do not change the timerange for the chart
We are getting data from PLCs onto Kepware, then using the OPC UA Extractor to send that data to FTDM. Once the data is in FTDM, I have another application that consumes data from it. The issue is that we are getting an array of boolean values in Kepware. If we extract the array values, the number of tags becomes too high. Therefore, we are looking for ways to transform or encode the array into a singular timeseries. Our initial idea was to convert the array into a string, then converting it back to an array in our application. Another idea is to encode the array into a single large integer. But I can’t see any avenue of doing either of these in the extractor. Any ideas on how to do so?
When dropping a file from your desktop/drives into Canvas, the file size increases. As one example, it went up 30 times; from 84kb --> 2520kb (without the canvas coverpage). The file size change makes it difficult to download the canvas, as it gets stuck. The end users cannot download the canvas they create and therefore are prone to stop using the platform.
Hi Team,It was observed that List and Search queries have some functional limitations which are handled explicitly by teams. Below are the expectations: Search queries must support pagination, enabling users to retrieve results beyond the current 1000-record limit. Pagination should include a cursor or offset mechanism, allowing seamless navigation through large datasets without data loss or duplication. List queries must support case-insensitive filtering Users need substring search over large datasets, which is not fully supported. Can we provide feature like "Contains" which will allow substring search.Thanks,Rahul

Cognite Data Fusion (CDF) appears to enforce a limit of approximately 200 Azure AD group memberships when resolving permissions for Service Principals. This limitation does not exist in Microsoft Graph, which supports retrieval of all group memberships associated with a user or Service Principal.As organizations scale their authorization models using Azure AD groups, this restriction can prevent access inheritance from functioning as expected and requires manual workarounds that increase operational overhead and governance complexity.Business ContextMany enterprise deployments use Azure AD groups to manage access to assets, plants, data products, and other resources within CDF.A common architecture relies on: Azure AD groups representing access domains. Group Object IDs mapped to corresponding Source IDs in CDF. Service Principals inheriting permissions through group membership. However, when the number of group memberships exceeds the current supported threshold, some memberships
