QUESTION
I tried all in this main step resource, but I cannot get leapmotion to work in MRTK. I download the foundation packege with the Mixed Reality Feature Tool but I keep getting this error in the editor while making the leap motion profile:
And this when I trytointegrate the module:
On the other hand when the core packege isimported as adviced "Only import the Core package within the Unity Modules" these errors appear and the project does not compile:
Unity version: 2020.3.11.f1 and installer both installers Leap_Motion_Setup_4.0.0+52173 (orion) and Ultraleap_Tracking_Installer_5.4.5_win64.
The departing repo is: https://github.com/microsoft/MixedRealityToolkit-Unity
...ANSWER
Answered 2022-Mar-18 at 11:26Which version of MRTK are you using?
I see you've tried both Orion (V4 service) and Gemini (V5 service).
You need to match the correct version of the Ultraleap Unity Modules / Plugin with the correct version of the Ultraleap tracking service (Orion/Gemini). Tracking Service version >=5.2 should be used with the Ultraleap Unity Plugin V5.3.0 (that exact version), although it will likely work with 4.9.1 of the Unity Modules too (I haven't personally tested this). This support is not yet in an MRTK release yet although it has been merged to main (https://github.com/MicrosoftDocs/mixed-reality/pull/512).
The update to the MRTK documentation to support the Ultraleap Unity Plugin V5 (requires V5.3.0 plugin) is in this pull request: https://github.com/MicrosoftDocs/mixed-reality/pull/512 and is worth a read.
Note, we talk about the V4 Unity code as Unity Modules and V5 Unity code as the Unity Plugin.
If you need to use the Orion tracking service then you need a Unity Modules version that is older than V4.9.1 - i.e. Unity Modules 4.8.0 from here https://github.com/ultraleap/UnityPlugin/releases/tag/UM-4.8.0
Sounds like you might still be having issues using Orion and Unity Modules - can you confirm the version of MRTK and Unity Modules you were trying to use please?
Summary:
Orion Service V4.X : Use <=V4.8.0 of the Unity Modules
Gemini Service >= V5.2 : Use V4.9.1 of the Unity Modules or 5.3.0 of the Unity Plugin (support for the latter is not in an MRTK release but has been merged to main)
QUESTION
I am trying to save multiple data entities in historical database, but only the first one from the array is saved in Mongo historical database. Below are the steps I performed.
Docker-compose for Cygnus:
...ANSWER
Answered 2022-Mar-08 at 08:35A first impression. At subscription you are using: "throttling": 5
throttling: Minimal period of time in seconds which must elapse between two consecutive notifications. It is optional.
That implies that just ONE notificación will be send in every 5 seconds time window. With your NGSIv2 batch update surely all notification will fall in the 5 sec window.
Try to remove that property.
QUESTION
I am trying to save historical context data in Mongo, but without success. Only the first payload sent to Draco is saved to MongoDB for historical data, but Mongo does not react to attribute updates. Versions used for the test: Orion-LD version 0.8.0, Mongo version 4.4, Draco version 1.3.6. I tested it also with the 3.4 version of Mongo and the behavior is the same.
Can you, please, help me to fix a problem?

Answered 2022-Mar-04 at 10:35We do not use that precise stack, but we have got many production deployments keeping context historical data on MongoDb by using FIWARE Orion (v2 API) with FIWARE Cygnus (NGSIMongo Sink for historical raw data, and NGSISTH Sink for aggregated data at MongoDB).
Maybe this help.
QUESTION
I just started using FIWARE and I'm having trouble with the data I want to persist on MongoDB. I want to use STH Comet in minimal mode. I am using a Python script that creates my context data with a specific id and then updates certain attributes of this data. While I can't see any problem when I observe the JSON data from this script, and HTTP requests but MongoDB keeps only the last updated version of this data in the related collection. In addition, the "sth" labeled collections does not show up. However I can see the "credate" and "moddate" metadatas in attributes. But I need different records for every update.
Here is the first POST request that I send to Orion to create context data:
...ANSWER
Answered 2022-Mar-04 at 11:01To put it simply, I realized that the problem I was experiencing was due to the parameters that I did not change in the config.js file of the STH Comet I set up on the remote server.
So, I changed the host parameter (from "localhost" to the "server's own IP") in config.server part and the URI parameter (from "localhost:27017" to "serversIP:27017") in the config.database part in the file.
The system is now working as expected.

QUESTION
How do I delete a flow defined in prefect orion? For example, I have multiple flows visible in the Orion's dashboard, some of which are no longer useful for me. How do I delete some (but not all) flows?
ANSWER
Answered 2022-Feb-14 at 16:11The only way to do this at the moment is through the REST API: https://orion-docs.prefect.io/api-ref/orion/api/flows/#prefect.orion.api.flows.delete_flow
It has yet to be hooked up to the UI.
QUESTION
I am making a Javascript program and on of the functions is to convert altitude/azimuth to right-ascension/declination given a time and latitude. My code can find the declination fairly accurately, I checked with Stellarium. I have been using this site to help me with the math.
My program gives me the wrong value for horizontal ascension which I plan on using to find right ascension (I already have a function to find local sidereal time which works). Here is my code for the equation
var ha = asin(-sin(az)*cos(alt) / cos(dec)) * (180 / Math.PI); this code is in Javascript but I defined custom sin/cos/asin functions that take degrees as input and return radians because that is the form my data is in.
The site I use also says that this equation should give the same result
var ha = acos((sin(alt) - sin(lat)*sin(dec)) / (cos(lat) * cos(dec))) * (180 / Math.PI);
but, the two equations give different results and neither are correct according to stellarium. I have checked that all the variables I am putting in are correct and I am almost certain I entered the equation correct. Here is the full code on github. I need help figuring out how to fix this problem.
--Note this can be run with node js with no libraries
The result I get is { ra: [ 23, 57, 37.9 ], dec: [ -5, 24, 38.88 ] }
It should be getting { ra: [ 5, 36, 22.6 ], dec: [ -5, 24, 38.88 ] it does not have to be exact, I only really care about the first number of ra (right ascension). It is also formatted in HMS format. The datetime is hardcoded to Febuary 1st 2022 12:00:00 so that is what you should set stellarium to if you are testing this out.
Here is the relevant code

Answered 2022-Feb-04 at 02:02Give the following a try. Notable changes include:
Specified 'GMT+0000' when establishing J2000.0 date, in addition to the date being passed in to
altazToradec(). Otherwise, new Date() returns local time.Sourced calculation of 'DEC' and 'HA' from MathWorks.com (look under the "Functions" tab).
NOTE: 'HA' and 'RA' are in degrees, not hours. To convert to hours, multiply by (24 hrs / 360 deg), or simply divide by (15 deg / hr).

QUESTION
Hello I'm trying to launch the FIWARE orion context broker using an atlas mongodb
...ANSWER
Answered 2022-Jan-20 at 12:07Orion currently supports only mongodb:// connection strings, built from the -db, -dbhost, -rplSet, -dbTimeout, -dbuser, -dbpwd, -dbAuthMech, -dbAuthDb, -dbSSL and -dbDisableRetryWrites CLI parameters(or default values, if omitted) as can be see in the source code.
There is an issue in the Orion repository with the aim of making this more flexible, allowing to provide the connection string directly overriding the above parameters.
While that issue comes (contributions welcome ;) you could hack the Orion source code cited above to build an specific version for you with support for mongo+srv:// connection strings.
QUESTION
Hello everyone, after completing the tutorials on NGSI-LD at: https://github.com/fiware/tutorials.NGSI-LD/ I am currently trying to implement my datamodel and facing multpile issues.
First I know what JSON, JSON-LD and NGSI-LD is and the basics of how the context broker and the MongoDB work together.
My Problem is how to setup such a project. I didn't find any tutorials on how to setup a project. The main points i need to know are:
- How to setup the orion context broker
- How to provide the context File to the Context Broker
- How to setup MongoDB
- How to connect all of the above together to a project
For now I have tried to convert my datamodel to json-ld and ngsi-ld using the tutorial at: https://github.com/FIWARE/tutorials.Understanding-At-Context/tree/ba6ac22ce329ed8eaac6ef5f01266048dc84d244
Afterwards I deleted the datamodel from a tutorial like CRUD-OPerations and inserted my datamodel. But when I start the tutorial and make a POST request it accepts any data, ignoring the datamodel. I could create entities which do not exist in the datamodel with non-existing attributes. The same problem occurs if i start one tutorial with the default datamodel. So it seems to always ignoring the context-File.
Further after i have written some data with POST and read with GET (which both worked perfectly) and close the project the next problem occurs. After I restart the tutorial all data i have written is deleted.
Am I not really getting the whole point of FIWARE or did I do something wrong?
I would appreciate any info from links to detailed explanation.
...ANSWER
Answered 2022-Jan-14 at 09:15As described here, the NGSI-LD interface is a flexible API which outputs various JSON and JSON-LD formats and is used for data exchange. The tutorials are describing the correct use of the interface only. They do not cover production deployments.
After I restart the tutorial all data i have written is deleted.
The tutorials are just that - they start from a clean slate. The Mongo-DB instance in the docker-file does not have a persistent volume and cleans up after itself.
it accepts any data, ignoring the data-model.
That is because JSON-LD @context isn't used to validate JSON data - you need a JSON schema for that. Technically the @vocab element in the NGSI-LD core context @context file pushes any unknown elements onto the so-called default context https://uri.etsi.org/ngsi-ld/default-context/. The @context file is simply providing a mechanism to standardize the attribute names into IRIs. Assuming you have created a Swagger/Open API file for your use case, then you can use the Swagger editor to generate server or client code stubs. Doing this in Java say, will result in a POJO which just accepts the attributes of your model.
How to setup the orion context broker
You could use the docker-compose provided as a basis for getting started, but for proper large scale deployments on Kubernetes, the provided Helm Charts are recommended. The Orion-LD documentation goes into more details.
How to provide the context File to the Context Broker
You place the @context file on a public web server. How you host your @context file is up to you. The tutorials use HTTPD for this purpose. The main idea behind an @context is that you are publishing an agreed set of IRIs which correspond to the attributes in your data. Smart Data Models, Schema.org, GS1 and plenty of other bodies generate IRIs, you should reuse them and link to them or publish your own @context describing your own world.
Once an @context just append the Link header to each context broker request.
