Hi Frans,

I think this is a great modification, is there a place where I can edit 
this ?

Hi Bart,

Here is a proposal for a merged use case:

Using spatial data during emergency response operations
Emergency response services in the Netherlands use SDIs to help manage 
large scale incidents. Predefined geographical data from their GIS 
warehouses can be used, but incidents and accidents are by nature 
unpredictable so it is impossible to determine beforehand which data are 
needed. In-house data need to be supplemented with data from other sources 
based on ad-hoc requirements. Typically, supplemental data are available 
through WxS services. This poses several problems:
1.      Third party data lack semantics in the sense of the Web of data. 
Under the umbrella of various projects a first attempt has been made to at 
least share definitions of the terminology used by various emergency 
response services, both national and cross border. This resulted in the 
start of a project called the Firebrary. Now the terminology and 
definitions are available on the Web as linked data as SKOS. Still linking 
from the spatial data to these definitions and vice versa is not 
standardized. Publication of web semantics with spatial data would improve 
discoverability of applicable data and facilitate linking data from 
separate sources.
2.      It is not possible to predefine relationships between Web data and 
data exposed through WxS services (rdfs:seeAlso is considered by many to 
be too limited).
3.      It is not easy to share all data related to an incident as Web 
data.
Being able to plot and exchange data about active incidents through the 
Web and visualize them in GIS tools with open standards would be a huge 
leap forward for emergency response services.
Related deliverables: best practices
Related requirements: Compatibility with existing practices,  
Discoverability,  Spatial metadata,  Linkability, Spatial relationships 


I changed the title a bit so that it better covers the use case. Also, I 
have added the Spatial relationships requirement to the list of related 
requirements. 
About that: the bit that I have not included yet is about types of 
relationships. In the existing use case it says "A related issue is that 
the relation between the data in the GIS warehouses is only spatial, while 
most of the time there is an administrative relation as well."
Which GIS warehouse do you mean in this case? The GIS warehouses of the 
emergency response services or those of the third parties whose data you 
would like to use? And how is not possible to have administrative 
relations now?
Regards,
Frans

Hi Frans, 

I'm sorry that I've missed this email. 

What I tried to explain is this, currently the emergency response services 
only use GIS services available in their GIS Warehouse ( feel free to use 
standard terms ). 
However during incidents there might be spatial data available at 3rd 
parties, this data could be in a external SDI or even in Web Data. 
Currently there is no easy way to find the data and integrate the web 
based spatial data 

The second part of the problem is that the spatial data which is presented 
does not contain any form of semantics as explained in my second 
submission. 
So even if we would be able to find and use external data ( both GIS / Web 
) we have no clue what it exactly means.

Hello Bart, 

In the process of trying to merge the two texts I came across something 
that seems inconsistent. In the existing use case it says "During 
emergency response operations in the Netherlands the only spatial data 
available to emergency response services are the predefined data in their 
GIS warehouses" and in the new text it says "During those incidents they 
[emergency response services] will use a wide variety of spatial data 
created and curated by third parties".  

Are the predefined data in the GIS warehouses of the emergency response 
services the same as spatial data created and curated by third parties? Or 
are they different data sources? I hope you can clarify this. 

Greetings, 
Frans

Sounds good to me!

Hello Bart, 

Shall I propose a merged text for the use case here in this thread?

Hi Frans, 

Sorry, I seem to have missed this email completely. 

Having just one use case who covers it all is fine for me. 
How would you like to proceed on this ?

Hello Bart, 

I realise this use case describes something not entirely covered by the 
existing emergency response use case, but do you think we could try to 
merge the new use case description with the use case already in the 
document? As far as I can tell, the related deliverable is Best Practices 
in both cases and requirements following from the use cases seem to be the 
same too. 

Regards, 
Frans

Hi all, 

As discussed on the call last week. 
ACTION-85 is about best practices on linking WxS with linked data, I 
created a use case to explain why this is important. 

Use Case. 

Emergency response services use SDI's to help manage large scale 
incidents. During those incidents they will use a wide variety of Spatial 
data created and currated by 3rd parties. Although the data provided by 
these 3rd parties is available through standard WxS services, these 
services lack the semantics of the thematic data. Currently there is no 
way for a WxS service to expose the semantics of the features it provides 
in a web of data way. 
If WxS services could be extended to provide the references to the 
semantic meaning of the features, the usabilty of these 3rd party services 
will greatly increase. 
By exposing the feature data as web data it should in the same time 
increase the discoverabilty of this data. 

Requirement: 

Link traditional WxS features to their web data counterparts
