[GeoNetwork-users] Sort RSS by update metadata date

GeoNetwork GeoNetwork User

Hello,

I am quite disappointed because I really don't know if there is a possibilty to sort, in the RSS flow, the metadatas by update date.

From the last updated to the older.

This manual page describe things like search by notinh as simple as a sort :
http://geonetwork-opensource.org/manuals/trunk/eng/developer/xml_services/metadata_xml_search_retrieve.html#rss-search-search-metadata-and-retrieve-in-rss-format-rss-search

Is it possible ?

I'm using GeoNetwork 2.7 / 2.9

Hi Maël

You can send the parameter sortBy=changeDate, rss.search accepts the same
parameters as the xml.search service.

Thanks for your (speedy) answer.

Uh ?
It changes nothings to the sort :

<?xml version="1.0" encoding="UTF-8"?>
<request>
  <sortBy>title</sortBy>
</request>

or

<?xml version="1.0" encoding="UTF-8"?>
<request>
  <sortBy>changeDate</sortBy>
</request>

or

http://geosource.local/srv/fre/rss.latest?sortBy=changeDate

The idea is to get the same results as this SQL query :
SELECT *
FROM `metadata`
ORDER BY `metadata`.`changeDate` DESC
LIMIT 0 , 30

Ideally, I want to get :
- change data
- title
- resume

Best regards from Britanny,

Hi

I'm trying these requests and get different results:

http://localhost:8080/geonetwork/srv/eng/rss.search?sortBy=title
http://localhost:8080/geonetwork/srv/eng/rss.search?sortBy=title&sortOrder=Asc

http://localhost:8080/geonetwork/srv/eng/rss.search?sortBy=changeDate
http://localhost:8080/geonetwork/srv/eng/rss.search?sortBy=changeDate&sortOrder=Asc

rss.search (and xml.search) use the lucene index for searches/sorting, no
sql queries.

If you don't need a rss feed, maybe is better to use the q service, similar
params as xml.search and returns a xml document with metadata information.

Regards,
Jose García

Well well.

I'm working with GeoSource 2.9.1 and I cannot obtain differents result sets.
But I tried on a GeoNetwork (2.7 ?) : il returns differents result sets when
changing the request.
I report this bug.

Thank you very much.

I really need a standard RSS feed for relay to several website.

Another question : is there a way to get the thumbnail of the dataset when
the metadata use an url ?
=> graphicOverview/MD_BrowseGraphic/fileName/CharacterString

A better question should be : how to create a more "clean" RSS feed, closest
to things like that :
http://rss.nytimes.com/services/xml/rss/nyt/Europe.xml

with :
- title
- url link to the metadata
- url link to the thumbnail
- latest modification of the metadata
- creation date of the data ?
- revision date of the data ?

Sorry for asking all about this.
