Hello,I am using OPC UA extractor to bring in sensor data in my cdf project. I want to limit the number of tags I am bring in from the source. I observed that in the PI extractor there is capability to include or exclude tags. Is there a similar filtering capability in OPC UA Extractor?

If I want to establish a relationship between a specific data model (not the core or enterprise model) and assets like a "function location," Do I  necessarily need to bring all the views from the core or enterprise models into your domain data model?The goal is not to extend the core model but to create a reference from my domain data model to the asset, possibly using node_reference.For instance, if I have an inventory and want to relate materials to a local storage (which is represented as an asset in the enterprise data model), could I define a property in my domain model that references the enterprise asset.Example:graphqltype StorageLocation { location: String plant: CogniteAsset # Reference to the asset in the enterprise model } In this case, I am just creating a link between my domain model and the asset without needing to extend the enterprise model or bri

Hi all,I am building a solution model on top of  a domain model we already have in place for a project.The domain model contains all the instances we have in the project, but this consumer is only interested in a subset and would like some filters in place to ensure that they are only getting the subset of interest. One of the requirements is that a certain property is according to their project standards and has a minimum length for a property. I see that there is a Range filter to check if a numeric property’s value is within a specified range, but is there any way I can add functionality to get the values length for this property?

 I have created 1 workflow , in which I am creating dynamic tasks depending on input, it creates batch of ids and create tasks out of it. Below is workflow definitionWorkflowVersionUpsert(   workflow_external_id="test_dynamic-0729",   version="1",   workflow_definition=WorkflowDefinitionUpsert(       description="This workflow has two steps",       tasks=[           WorkflowTask(                external_id="test_sub_tasks",                parameters=FunctionTaskParameters(                    external_id="test_sub_tasks",                    data="${workflow.input}"                ),                retries=1,                timeout=3600,                depends_on=[],                on_failure = "abortWorkflow",            ),           WorkflowTask(                external_id="test_create_sub",                parameters=DynamicTaskParameters

I’m using n8n AI agent builder to query CDF via an http request. The body of the request is:The request URL is https://westeurope-1.cognitedata.com/api/v1/projects/essc-sandbox-44/events{ "filter": { "startTime": { "min": 1751070336000, "max": 1751588736000 }, "dataSetIds": [7726848970162689] }, "limit": 1000}CDF seems to recognize the datasetid filter but not other filters like starttime as shown or others like Types. The result set returned is all events in that datasetid.I’ve also tried minstarttime and maxstarttime.ideas?  

Hi All,We are encountering an issue after uploading E57 point cloud files into Cognite Data Fusion (CDF). The rendering quality of the images is quite poor, and we're unsure if we're making a mistake during the upload process.Has anyone else experienced similar issues? If so, do you have any solutions or recommendations to improve the image quality for point cloud in CDF?Please feel free to share your insights and suggestions.Thank you!

hello guys, I wonder how do you populate data model directly from the dataset? so i have ingested all my timeseries data into my dataset and then i want to run transformations using this dataset as a source but how do i get the actual values from the data points and can you filter just to extract certain timeseries data? this is the query i am running at the moment: select  cast(`externalId` as STRING) as externalId,  cast(`name` as STRING) as name,  cast(`description` as STRING) as descriptionfrom  `_cdf`.`timeseries`; what i want really is to import all my timeseries data from my dataset into my data model and then continue building. 

I have a question about contextualization.In my setup, I have a functional location with a machine, and under the machine, there's a sub-station. When I contextualize a document related to the sub-station, why isn't it directly linked to the machine level and the functional location? I understand that I manually contextualize it to the specific station, but since the station is part of the machine and the functional location, it should appear there too.I think there's a missing link in my data modeling between the functional location, machine, and sub-station. What methods can I use to ensure that when I contextualize a document, it shows up at all levels of the hierarchy linked to that machine?

Hey everyone! 👋 I've been diving into the world of CDF data modeling for the past couple of weeks, and I thought I'd share what I've learned so far in a way that's easy to understand. First off, let's talk about the term "Data Modeling." It's everywhere in CDF - in API endpoints, UI, docs - but its meaning can vary depending on where you look. After some digging, I've figured out what it means specifically in CDF. Essentially, it's about organizing, storing, and working with data in a way that's perfect for handling complex industrial scenarios. Think of it as the foundation for unleashing the power of Cognite Data Fusion on your industrial data. So, what exactly makes up a Data Model in CDF? Let's break it down: Space: Think of it like a folder where everything in a Data Model hangs out. Containers, views, instances - they all belong to a Space and have their own unique ID. Containers: Th

Hi,I would like to update data to the EDR. The EDR has a build in tool to upload data, but I would like to use the API. As I understand it is not officially supported, but we would like to give it a try as we have hunderds of files we would like to upload.Before I asked my questions by e-mail, but I am directed to this hub to ask my questions, so there we go: File upload:I'm using the client.files.upload() function [1]. It seems to work when only the file path is provided, but I'm unsure whether this is sufficient or if I should be populating more of the optional arguments. Here's what I'm looking at: path external_id name source mime_type

Whose idea was it to hide the dropdown behind the filters? 

Does it make the data available for optimal maintenance scheduling, or does it automatically generate maintenance plans based on that data? Does it predict failures?

Hi all,I have a question regarding the use of nested attributes from linked objects when defining indexes.In my model, I have an object Cement that has a direct link to another object called ScenarioContent.I would like to use the attribute ScenarioContent.Type as part of the index on the Cement object.This is particularly useful, because I use views that filter Cement instances based on ScenarioContent.Type. For example, to expose only planned scenarios, I use the following rawFilter in a view:@view(  rawFilter: {    nested: {      scope: ["Cement", "ScenarioContent"]      filter: {        equals: {          property: ["ScenarioContent", "Type"]          value: "PLANNED"        }      }    }  }) Question:Can I use this nested attribute (ScenarioContent.Type) in the index

Hi, I did run transformation of assets and it worked first time successfully but today when I had a look, found a failed run and looking at logs, it says below error: Request with id 0b54c004-c667-9eab-a8c3-0a0047128fe1 to https://westeurope-1.cognitedata.com/api/v1/projects/cdf-ABCD/models/instances failed with status 400: Duplicate node externalIds for space 'icapi_dm_space' present in request: OSPRFIDRTO109:off_spec. Any idea how to fix this? and what is this error actually? 

Hi Community,I am using a toolkit and I am doing some transformation from RAW to the Data Model. From the Documentation Online, I only see example on how to apply the toolkit transformation to legacy tables (assets, events, timeseries,etc)This is sample of transformation format for toolkit:  Anyone know what is the configuration if we want to transform to Data Model? How to apply the space name and external id? Thank you.

Hi everyone,I'm currently using a nested filter in my view, and everything seems to work correctly — except in the tabular view.Here’s what I observe:In the tabular interface, the table shows 0 objects. However, when I click into the table, I can actually see that the instances are present. 

Hi Hub, We have some backend code running as a Github Action that fetches events using `clients.events.list` over a period of 1 year. The fetching is of course chunked into smaller time frames to avoid memory overload. This has worked just fine until recently where we are frequently encountering aCogniteReadTimeouterror, which can be traced back to the following HTTP request error:requests.exceptions.ReadTimeout: HTTPSConnectionPool(host='az-ams-sp-002.cognitedata.com', port=443): Read timed out. (read timeout=30)The error occurs inconsistently and not necessarily at the same point in time of the workflow run. Have there been any recent changes/restrictions in the Cognite SDK that could explain the cause of the issue? As mentioned, some weeks ago the workflow succeeded without problems. For additional context, we are using multiple threa

I noticed a few misses / potential improvements in the alerts & monitoring section of Cognite charts - Was wondering if anybody else had similar experiences?Email alerts always come in UTC (Considering we are based out of India, we may miss important alerts because of this). Let's say I have an Asset where I have generated a chart (in our case a particular well from a particular lift type showing critical parameters). A filter-based option where I can just switch Wells showing - using the same parameters as tagged before.
