Hi Team,I'm using the Cognite Toolkit to test the CDF download raw functionality. I’ve observed that the download process fails when the staging database name contains a special character such as :.For example, if the database name is state:odbc, the cdf download raw command fails because it attempts to create a temporary folder with the same name as the staging database. Since : is not a valid character for directory names, the folder creation fails.Additionally, when I try to download the raw data from another database (without special characters), three files are created in the temporary directory:.Table.yamlManifest.yamlRawRows.ndjson.gzCould you please confirm if the RawRows.ndjson.gz file is expected, or should the output be in .csv format?

Team, can someone help with this ?Customer Context:“We implemented Datamosaix primarily to collect compliance related data for our facilities and to give access to those personnel to pull data.It varies on which reporting agency this is for but they typically produce reports in csv format that is for one month at a time, on a strict 5min or 1min interval starting at midnight on the first day of the month.We've been using the PI trend tool previously and would like to produce reports in a similar way.”******************************************************************************Customer End to End Flow:-This data is coming from FT Historian, which is collected on deviation not time. -The purpose of DataMosaix in our use case is to give access to Compliance personal to pull data. -They need data produced at specific time intervals.  One example may be every 5 minutes  for an entire month for 20 different tags  per site.  This needs to start at midnight and end at midnight on the first da

During the calculation of adding two time series, if one of them has no value, will the calculated timesseries give me some interpolated value?In the example below, the ‘Error Intern’ series has a value of 2252, but in ‘Total Down Time’ I’m getting 2756.64, which is incorrect—it should also be 2252.Why is it still giving me a linear interpolation value even though I selected the interpolation type as ‘step’?  

Hello, Although “unitless” is an alias of the dimensionless:unitless unit, try_get_unit(“unitless”) returns null.ref: https://github.com/cognitedata/units-catalog/blob/main/versions/v1/units.json#L1699 Could you please have a look? Thanks!

I’m searching for a specific document using Search. The doument ID is hidden in a metadata tag.If I search for this document ID in the search bar, the file is not discovered (obviously it doesn’t search in metadata)Plan B is to use the filter (which is inconvenient since it forces me to know that particular metadata key)The metadata key is document:abp_document_number, but it doesn’t show up when I search in the filters  If I use the Data explorer under Data management, it discovers the metadata key, allowing me to filter on it  But there is an even better way of doing this in Data explorer. There I can edit the search settings and instruct it to look in the metadata. Then it discovers it immediately. This allows me to find the document without having to know to filter on this very cryptic key. For classic data model, where a lot of info is dumped in metadata, with poor governance on the keys, the ability to search in metadata is VERY useful   

What are the licensing terms and conditions for using Cognite's Open Industrial Data? Could you please provide a link to these terms and conditions?Thank you.

Can we visualize Visio files with.vsd extension in Industrial canvas?

What capabilities are required to run a transformation using client credentials? I have a client_id and client_secret that when I add to the transformation and hit ‘Test credentials’ it says ‘Credentials verified’. However when I run with client credentials I get an error: Transformation job could not be created. Error code: 403 API error: Invalid source/destination credentials: Token did not provide access to project kuraray-america. Request ID: eb5136ee-594d-971f-b27a-7be0d1a60b15these credentials are a part of a group that that has read and write capabilities to:transformations sessions datamodelinstances (that is what this particular trasformation is creating)Additionally I am part of the same groups as this client_id, and I am able to run the transformation using ‘run as current user’ successfully

Hi everyone,I have a question: Can we use data from Data Models in Canvas?Is there any way to visualize that data available in Data models into Canvas?In our case, we are using Cognite Charts with time series data coming directly from machines (e.g., good parts, bad parts). However, the time series does not include product or batch information, which we do have in our Data Model.Is there any possibility to link both sets of information together for analysis?My initial thought is: if I can bring the required data from Data Models into Canvas and then create charts there, it would make the analysis much easier.But I’m not sure if this is possible—or if there’s another approach you would recommend.Any suggestions or best practices would be greatly appreciated!

With the Java-SDK, I don’t see an option to supply the client-name during initialization of the client.  https://statics.teams.cdn.office.net/evergreen-assets/safelinks/2/atp-safelinks.htmlIs there anyway we can do that? We need the client-name for logging purpose. 

We are using the cognite core data model and we extracted historian data which has been created as a bunch of time series. Now we have one asset that we would like to link these time series to. How do we do this?Please help, thanks.

Hi,We are looking into contextualizing our data models with 3D info, based on the relevant concepts/types from the Cognite Core Model. However, we ran into a limitation that as far as we can see severely limits the usability of the functionality as is.The CogniteCADNode has a direct relation to a Cognite3DObject, that can be made up of multiple CogniteCADNodes, reflecting that an asset may correspond to multiple nodes in the 3D model. That makes sense. However since the link from CogniteCADNode to Cognite3DObject is a single direct relation, the current model does not allow a CogniteCADNode to be part of more than one Cognite3DObject, which typically is meant to correspond to an asset. That is unfortunately in direct contrast to reality. One CAD node belonging to many different assets/objects is not an edge case, rather, it is the norm, at least for Aker Solutions.Have we correctly understood the current functionality? If so, are there any plans to amend this limitation? Do you have a

Hi everyone! When importing data for a specific TAG, I notice multiple connecting lines or links between TAGs across the same P&ID. What steps can I take to minimize or reduce these connections?”

On the platform, when we have more than one annotation on a file, if they are very close to each other (overlapping by a pixel or two), the platform shows the overlapping box so we can select the correct annotation.I understand this as a bug.See the images below:The tags PB2885C and XA2885C are very close to each other. The overlap between them is barely noticeable.However, when you click on either one, both tags appear in the overlapping box:I’ve seen this happen every time we have annotations that are very close to each other.For a better user experience, it would be ideal if, at the moment of the click, the platform could understand that only one annotation is actually inside the click area.This would prevent the overlapping box from appearing and would solve the issue.Is this something we can have fixed?

When setting up schedules and such for task. I can’t figure out how to toogle use normal human understandable explicit time (24:00 the 24 hour clock). only US and UK uses this AM PM thing, the rest of the world is only confused with the this thing. After midday or after midnight and “Pefore” Midday og “Pefore” Midnigt. yes i know it some obscure latin “ante” and “post” meridien wording that is different. but for the rest of us that don’t use this in our day to day. it is just a source of confusion.But please have a way to use the explicit time (24:00) hour. and not the implicit time this is just confusion and a bad experience.  

Hi Everyone,Is there a way to create an alert directly on a calculated series in Cognite Charts?From what I’ve found, to create an alert for a calculation, I first need to schedule the calculation and then run the alert on that scheduled result. However, scheduling doesn’t seem to work well in my case.For example, if I receive machine data every hour, I also need to schedule the calculation every hour. Sometime scheduling stops by itself. It would be much easier if we could create alerts directly on the calculation without scheduling.Secondly, I’m not finding clear documentation or videos on how to schedule calculations properly and what best practices to follow. If anyone has experience with this or can share guidance, please let me know.Thanks!   

Hello, When I’m connecting to the virtual machine Ubuntu, I’m facing a pop-up “connection failed”. It seems that my internet connection is not set up, do you have any idea to do so ? I’m not able to do rest of the training without connection. Thanks

Hi Everyone,I’m trying to sum up all the values in my data points for a daily total. However, the Resample to Granularity function doesn’t seem to work properly on my side. Also, I noticed that we can’t select a custom time frame in this function — for example, if I want to sum values between specific hours, that option isn’t available.Is there any other function that allows summing all data points within a specific time range?One more thing: I find the Statistics window for each time period very useful. Wouldn’t it be great if we could also have a Sum value displayed there?   

Hi Everyone!I need to manage streamlit applications (read / update files) using the Cognite SDK or with the API.I was able to publish streamlit applications using the cognite toolkit, but I also need to read them.Tried searching the api-docs and cognite-sdk docs with no luck. Thank you!

Hi Team, we have data in format like list of externalIds and space as key and value.  Like list of Json object in data model. something like [{externalId:well,space:slb},{externalId:well1,space:slb2}]So can we keep a field in model like violatedEntities: [JsonObject]Is it possible to parse all the externalIds and store it like this?Thank you.

Hello,  Is it planned to support RAW querying via CDF Grafana Datasource ?  Thanks ! 

We are now planning to integrate a large amount of historical data. The context about historical data and our data organization is in this topic:We create an interface WellState, which contains 2 properties: WellId and Archived, in order to propagate the Archived flag to every object in our data models.After integrated large historical data in our development env, we found that DataFetchingException always occurred in Daily(550K lines) and Operation(2M lines) in using GraphQL. And if using cdf_nodes to load Daily and Operation, the transformation will be blocked util that your session is closed.Info: Daily has many relationships and Operation has only a relationship with Daily. But We have also other 3 objects like Operation(big dataset and a relationship with Daily), they can work well. GraphQL:query MyQuery { listOperation { edges { node { externalId space } } } listDaily { edges { node { externalId space } } }}the result is alwa

Hello, I have two questions:When using cdf_nodes in transformation, does query optimizer take advantage of the container indexes? What we notice is it is not the case.  How can we run broadcast joins in transformation.
