DevUI : Browser client Out of Memory error

[ansSanthoshM]

I could fire up the DevUI and run my multiagent workflow, but very frequncy i am getting Out of Memory error on my client browser UI ( i test in Edge and Chrome) both gives error, and server side i get message like below.

[CANCELLATION] Execution cancelled via CancelledError for resp_b3dd6c17
[CANCELLATION] Stream cancelled for resp_b3dd6c17

Upon reloading the webpage, my current workflow details disappears. Neither i can't send new message to start the workflow from begining. I need to kill the server (ctrl+c) and start the server again.

How to overcome this error ?

Great starting point! Let's look at two concrete examples from contexts.bitplan.com: the BookContext and CityContext. A full comparison page has been created at https://cr.bitplan.com/index.php/SiDIF_vs_RDF_Triple_Notations

Here is the instance from BookContext:

SiDIF:

LordOfTheRings isA Book
"Lord of the Rings" is Book_title of it
"0261102389" is Book_ISBN of it
"J.R.R. Tolkien" is Book_author of it
"Fantasy" is Book_genre of it

Turtle:

@prefix : <https://contexts.bitplan.com/index.php/> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

:LordOfTheRings a :Book ;
    :Book_title "Lord of the Rings"^^xsd:string ;
    :Book_ISBN "0261102389"^^xsd:string ;
    :Book_author "J.R.R. Tolkien"^^xsd:string ;
    :Book_genre "Fantasy"^^xsd:string .

N-Triples:

<.../LordOfTheRings> <rdf:type> <.../Book> .
<.../LordOfTheRings> <.../Book_title> "Lord of the Rings"^^xsd:string .
<.../LordOfTheRings> <.../Book_ISBN> "0261102389"^^xsd:string .
<.../LordOfTheRings> <.../Book_author> "J.R.R. Tolkien"^^xsd:string .
<.../LordOfTheRings> <.../Book_genre> "Fantasy"^^xsd:string .

The readability difference speaks for itself. The 4 problems discussed in detail on the comparison page using both BookContext and CityContext:

1. Blank nodes: SiDIF requires named identifiers — no blank node syntax exists
2. Namespaces/prefixes: Book_title, City_Population need URI mapping; CityContext has scope=Global with empty namespace
3. Literal types: Text→xsd:string, Date→xsd:date, Number→xsd:integer, External identifier→URI with formatterURI
4. Round-trip fidelity: addsTo, scope, index, mandatory, formatterURI have no RDF equivalent and would be lost
