Cardinal Directions in 3D (point cloud) to improve viewability / navigation of 3D modelNew

Users at ExxonMobil Baytown are requesting the ability to show cardinal directions in the 3D models and their associated viewing interfaces to improve ability to locate equipment in the field. There should be a north / south / east / west toggle to show or hide such that if the model has been geo-located that users can see directions related to true north.

Containers, Spaces and Instances

I have the following question regarding Containers, Spaces and Instances. Let's say I have a Container named Well in the space A and all its instances are created in space B. When I delete container Well in space A and recreate it (because I want to change a column name for example): Does instance in space B are deleted as well? If they are not deleted, If I rerun the transformation to populate the new container again in space B with the new schema (same external_id) what state should I expect my instances to be in ? A merge of old and new schema? What is the best practice ? To delete container in its space and its instances in all spaces also? Thank you!

Hosted Extractor run triggerParked

It would very helpful to have a way of triggering a hosted extractor run. I have an extractor that we only want to run once a day when in production but we are trying to build it out and test it. It is very slow development when we have to wait a minimum of 5 minutes for the schedule to trigger. If hosted extractors get a trigger feature then I see nothing stopping it from being used in workflows.

Support for Double-Byte Characters in Property NamesGathering Interest

Hello,We have confirmed that there is a restriction in the data model View (Container) definition that prevents the use of Japanese (double-byte) characters in property names.This limitation also applies to the Records/Streams API. Currently, our database column names and CSV file headers include Japanese characters, which means we are unable to use the existing names directly when registering these datasets as Records.As a result, we are now required to define a mapping between the Japanese column names and alphanumeric property names, and to establish, standardize, and manage a naming convention. However, this process is labor-intensive and may lead to confusion and operational burden in data utilization.Therefore, we would like to kindly ask if you could consider supporting the use of Japanese (double-byte) characters in property names within the data model View definitions and the Records API.

Establishing Relationships Between Domain Data Models and Asset

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 bring its full view into my domain model , works?

Use of CogniteDescribable in Data Modeling - core feature

This might be a basic question, but I often find myself uncertain about when to use CogniteDescribable in data modeling within Cognite Data Fusion.For example, let's say we have domain tables in our data model, such as MaterialType, which contains data from SAP and defines the types of materials we work with (e.g., code and description). In this case, would it be appropriate to implement CogniteDescribable to reuse common properties like name and description?What are the advantages of doing so? Does using CogniteDescribable provide any specific benefits—such as improved performance through indexing or partitioning—when used it containers?In summary, should I always use CogniteDescribable in these types of scenarios, or are there cases where it's better not to?

Ability to Process DGN'sGathering Interest

We are running into a very significant capability issue with Cognite where the platform cannot process DGN (Bentley Microstation) files. We (Marathon and the supporting Cognite project team) need immediate assistance with getting this resolved. Rachelle Harris requested I submit this ticket to help elevate the concern.

Granulated access for hosted extractorsNew

Having unscoped access rights will never not be an issue. It’s an issue for functions and it’s and issue fir hosted extractors. We want to avoid all or nothing accesses, giving write access to all hosted extractors would never be acceptable, giving access to subset however could be an option.And again, this goes for all resources that are not scoped. It greatly limits their usability in an production environment. Markus PettersenAker BP - Techniacal Domain Architect for CDF

Hosted extractors, missing and confusion UI elements

We would very much like for a new column to be added to this view, “extractor type”. Currently there are no indicators as to what type of extractor it is. For the developers working on the extractor this is not an issue because they know, but for others that just want an overview this is somewhat more difficult as we would need to click in on every single one of them to find out. Sometimes we would like to just see all REST extractors, or all MQTT extractors and so on. Another point is the throughput: “0 datapoints p/hr”What does the “p” stand for, is it “0 datapoints per hour” because if so the p is redundant as the standard use of “/” already signifies it. Also the SI unit for hour is h not hr. E.g.: km/h (km/t norwegian), m/s etc.

Point cloud rendering issue

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!

Data modeling transformations

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.

External ID doesn't work when copying from Fusion UI

The external id of some time series contains special characters. Should they contain special characters, no, but that is not the issue here. As long as CDF allows special characters in their ID’s it should also have support for them in the rest of the system. When you press the copy button in Fusion you don’t get the special characters, and without those characters the ID is invalid and cannot be used. Hence the copy button does not actually copy the external ID, it alters it and that is an issue.# The actual external IDLIMS_Skarv_Analysis 9-ion analysis_SP 44-AP-0027 - DS - 2. STG\xa0SEP_Param Sulphate, SO42-_Unit mg/l# Copied from Fusion UILIMS_Skarv_Analysis 9-ion analysis_SP 44-AP-0027 - DS - 2. STG SEP_Param Sulphate, SO42-_Unit mg/lThe fact that the external ids contain these characters to begin with is a different issue we are looking into.

Utilizing index in data model from a transformation

HiWe are testing out a new deletion transformation for a view in data modeling. The transformation looks something like this:select externalIdfrom cdf_data_models(...)where project in ("ProjectA","ProjectB")This transformation always times out and returns a “Graph query time out” error message. However, when changing the transformation to this the transformation just runs fine:select externalIdfrom cdf_data_models(...)where project = "ProjectA"unionselect externalIdfrom cdf_data_models(...)where project = "ProjectB"For context, the project column here is indexed and the view has around 10 properties and about 1.7 million rows. The transformations all query the same view.We are therefore wondering how the filtering in transformations handles filtering in data modeling and why these transformations are performing different. Learning more about this would benefit us greatly when working with transformations and data modeling in the future :)Thanks in advance!Sebastian

Cognite SDK and Google Colab

I’m doing the Data Scientist Basics Course using Google Colab, and I am experiencing the following issue when traying to retrieve a list: WARNING:msal.oauth2cli.authcode:Found no browser in current environment. If this program is being run inside a container which either (1) has access to host network (i.e. started by `docker run --net=host -it ...`), or (2) published port 53000 to host network (i.e. started by `docker run -p 127.0.0.1:53000:53000 -it ...`), you can use browser on host to visit the following link. Otherwise, this auth attempt would either timeout (current timeout setting is None) or be aborted by CTRL+C.
