[dspace-tech] Re: How to use External Links instead of Bitstreams? (Just like OAI with metadata-only option)

2019-10-04 Thread Bruno Nocera Zanette

Re-Posting my answer on dspace-commuity forum here just to give my final 
solution.

Based on your answers i've discovered that ORE is nothing more than a 
special XML bitstream, that define bitstreams as links. So i decided to 
write a Python class to create a "Simple Format Archive" packager using 
OAI. The packager receives a base URL and a handle and then make requests 
to OAI to gather item's metadata (DIM) and item's ORE information (ORE) and 
create a ZipFile with those infos. This ZipFile is ready to be uploaded to 
a repository using "Batch Import (ZIP)" option.

The code is in very early-development stage but it already does the job. 
Later it can become a real python extension, to accept a list of handles 
and different base url at once.

I've deployed it on heroku free plan just to test it. It can be accessed at:
https://dcorepackager.herokuapp.com/

And the source-code is stored at:
https://github.com/BrunoNZ/dc-ore-packager

Feel free to test it, and please let me know of any bug or suggestions.

[dspace-tech] How to use External Links instead of Bitstreams? (Just like OAI with metadata-only option)

2019-09-18 Thread Bruno Nocera Zanette

Hello, folks!

How can i manually add external links instead of uploading files?
I want to add some itens to an existing collection that only have metadata 
and to use external links instead of uploading a new bitstream. Most of 
these are links to bitstreams of other instances of Dspace.
It is the exact same thing that happens when using OAI Harvester with 
metadata-only option activated, but without having to configure an entire 
collection with OAI.

I've found in another post of "Dspace Community" 
 how 
to configure Dspace to not require to upload a bitstream, but it doesn't 
fully solve my question.

Is it possible to do it?

Thanks!

Re: [dspace-tech] dspace6 xmlui Error - 404

2016-11-21 Thread Bruno Nocera Zanette

Ahmed,
First of all, did you add "8080" to the address? If you didn't alter
tomcat's default options the correct address is something like:
http://[HOSTNAME]:8080/[INTERFACE]
(or https://[HOSTNAME]:8443/[INTERFACE] for REST-API)

So, if you're running it on localhost and you're trying to access xmlui
interface, the address is:
http://localhost:8080/xmlui

Besides that, it all depends on how you configured tomcat. If that's the
case, post your tomcat's config (remember to remove sensitive informations)
that we will try to figure it out.

Hmm.. It's a long time since i last did it and i don't remember the details
anymore. But i remember that i've followed the wiki and i also struggled
with this config files, and that in the end was just some minor details.

Later today i'll give it a try on my local instance to see if i get any
luck.
For now, let's see if anyone have more knowledge about it.

Donald,
This is the expected behavior for SOLR, for security reasons.

Take a look at this wiki to learn how to bypass this restriction:

Re: [dspace-tech] add new field on request form

2016-11-06 Thread Bruno Nocera Zanette

Have you tried this?
https://wiki.duraspace.org/plugins/servlet/mobile#content/view/19006029

It should work for jspui and xmlui (both mirage themes). You just need to
edit "input-forms.xml" and then restart Tomcat.

Also, please, don't use others threads with different subjects to make your
questions.

Re: [dspace-tech] problem user dspace

2016-11-06 Thread Bruno Nocera Zanette

Yeah, you could do something like that as long as you set the right
permissions for DSpace's installation folder. The rule is that Tomcat
always has to able to write on DSpace installation folder. So, for
instance, If you give permission for dspace group tô write on it and add
Tomcat to dspace group, you may be good to go. However you may have to set
permission masks to the cases when Tomcat create a file and then it will
own it, and not DSpace. Also, there may securitity issues that you have to
analyse carefully. But yeah, there are tons of solutions for this problem.

Re: [dspace-tech] problem user dspace

2016-11-05 Thread Bruno Nocera Zanette

Oh... I've forgot to say that this will only works if you really installed
DSpace inside "dspace" user. If not, i suggest you to change DSpace's
installation folder's owner to "dspace" user.

Lets say you installed it using "root" user on folder "/opt/dspace".
Everything that is created during installation process will then belong to
"root", and not "dspace". But it's not recommended that Dspace runs on root
user because security issues, and nor "tomcat". The correct way is that the
folder in which DSpace is installed belongs to a user other than "root"
(and other important services). That's why in the tutorial is suggested to
create a new user and to do all the installation steps using this new user,
so that everything created belongs to it.

If this is your case (installed everything using "root"), use "chown"
command to alter installation folder's owner to "dspace":
$ chown -R dspace:dspace /opt/dspace

Also, everything i said there is nothing to do with Database users. This is
a completely different thing, and it's not affected by none of the
suggested commands.

Re: [dspace-tech] problem user dspace

2016-11-05 Thread Bruno Nocera Zanette

Hoska,
You need to edit the file: /etc/default/tomcat8, to specify that Tomcat
will run from now on on the same user that DSpace is installed on. Eg: If
you created an user called "dspace", you have to configure Tomcat to run on
this user "dspace". This is necessary because otherwise tomcat wouldn't be
able to write to files inside dspace's installation folder that are
important for it to function correctly, like SOLR files and log files. All
you have to do is to change the line "TOMCAT8_USER=...", save and restart
tomcat.

Also, if you already ran Tomcat on another user, lets say "root", you will
need to change some folder's owner from "root" to the new Tomcat's user,
for the same reason explained before. Some of these folder are:

- /var/lib/tomcat8

- /var/log/tomcat8

- /var/cache/tomcat8

(there may be others depending on the OS, tomcat's version, configurations,
...):

To do it, use the command: "chown -R" (-R is to modify it recursively).
Eg.: if it's set on the configuration file that tomcat will run on user
"dspace" and group "tomcat8", the command would be:

$ chown -R dspace:tomcat8 /var/lib/tomcat8

After doing this, follow both dspace's and tomcat's logs to see if
everything is going fine.

Re: [dspace-tech] Fwd: [dspace-community] Authorization policy.

2016-10-26 Thread Bruno Nocera Zanette

Arjun,
If i understand correctly, you want to add authorization policies to each
Content (Community/Collection), right? Or those contents already had
policies and now they're not working properly?

If you just want to add policies, do the following:
1) Login with an admin user
2) Create groups of epersons that will be able to perform some action on
some content, accessing the option "Groups" on the right menu. (eg: Create
a group called "COMMUNITY_AuthorizationTest_READ" that will contain all the
people that will be able to read AuthorizationTest Community)
3) Access the option "Authorizations" on the right menu (right below
"Groups") and select the content that you desire to change authorizations.
4) Delete and Create the policies as you wish. (eg.: Delete the default
"READ action for Anonymous group" policy, that allows anyone to read the
content, and create a new READ action policy using the group created on the
step 2.)

I did these steps on "demo.dspace.org" instance (version 6.0), on the
community "Authorization Test Community", and it worked fine. You are not
allowed to read it unless you're logged into Submitter account. However, it
should also work on a Dspace 5.x instance, since this feature didn't
suffered any critical change on the update from 5 to 6 (afaik).

Re: [dspace-tech] Database Schema refresh

2016-10-07 Thread Bruno Nocera Zanette

Donald,

if i undertand correctly what you said, the commands bellow does what you
need:
$ ./bin/dspace database clean
$ ./bin/dspace database migrate

Take a look at this for more info:
https://wiki.duraspace.org/display/DSDOC5x/Database+Utilities

Basically it reset the database to the initial and re-create with
migrations. You will lose all bitstreams, metadatas, items/collections/

If there's anything to save you can export it with dspace's export options
and then import it after the reset:

Re: [dspace-tech] Can't create items through REST

2016-10-03 Thread Bruno Nocera Zanette

Ondrej,
The login method has changed on DSpace 6. Now, email and password must be
passed as a html queries, and it returns an JCOOKIE that must be passed
back to the server on every request. Also, the queries must be on HTML safe
format.

More info at:
https://wiki.duraspace.org/display/DSDOC6x/REST+API#RESTAPI-Index/Authentication

I've wrote an collection of bash scripts to test DSpace REST endpoints,
that you may take a look to understand it better:
Login: https://github.com/BrunoNZ/dspace-rest-requests/blob/master/login.sh
SendRequest:
https://github.com/BrunoNZ/dspace-rest-requests/blob/master/send_request.sh

Re: [dspace-tech] 20 million item repository with dspace

That is a LOT of items! How many requests per day/hour/... do you expect to
have? Is it in the same proportion of items?

I believe that the real problem is the quantity of requests, once the items
will only be another row into the database. But to query over them will be
a real challenge for Dspace!! Specially because it's not build to be
distributed on the cloud.

Keep us up to date with this, plz!

Re: [dspace-tech] REST Interface Sample App on Rails

2016-09-28 Thread Bruno Nocera Zanette

Hey folks,
I'm proud to announce that the interface is complete. Maybe there are some
few tweaks to be made, but overall it implements everything possible
(besides policies CRUD operations).

https://drcgem-sample-interface.herokuapp.com

Updates:
- Added a welcome page that shows an info and the site hierarchy;
- Added CRUD operations for Schemas and MetadataFields
- Fixed some bugs
- Fixed application style

Everything seems to be working very fine with Dspace6 Demo instance
(everything but Schema Creation/update because a REST API bug that have
been already fixed but not applied to demo instance).

This is not meant to be an official DSpace's REST interface but i think
it's a good example of what it can do and a good start point for other
projects, that is for me the greatest advantage of REST API. IMO, depending
on the situation, creating a simple app that implements a custom interface
is a better solution than customizing the whole interface. And to use the
default interface only internally to do admin stuff.

The 'dspace-rest-client' rubygem will be update in the next few days,
because we're still working to make both API verions 5 and 6 to work
alongside each other,  but for now you may use my repository's version (
https://gitlab.c3sl.ufpr.br/bnzanette/dspace-rest-client).

Cheers!

Re: [dspace-tech] Move logins from one machine to another

2016-09-23 Thread Bruno Nocera Zanette

Sakssham,
Since it's just a reinstall of an existent repo, you may achieve it by
pg_dump'ing the whole db and then restoring it on the new machine.
But there are some catches. You have to first install the exact same
version that you're actually running, then restoring the DB, copy the
installation folder, and test it. Then, you update the source code to
whatever version you want, compile it and update the installed
packages. It has to be like this because there may be some DB
migrations between the two versions that if ignored can crash your
system.

It's complicated to do a step-by-step guide. But it will be something
along the following lines:

[ON THE OLD MACHINE]
1) pg_dump -U [database-user] -f [backup-file-location] [database-name]
2) copy the installation folder to new machine (you can use "scp",
"rsync",  Or compress with "tar" and copy using a usb stick,..
however you like)
3) copy the source code folder to new machine

[ON THE NEW MACHINE]
1) create an user and a database
(https://wiki.duraspace.org/display/DSDOC5x/Installing+DSpace#InstallingDSpace-Installation)
1.1) restore the data using pg_restore
(https://www.postgresql.org/docs/9.2/static/app-pgrestore.html)
2) Verify the source code/installation folder and their location
2.1) You may have to recompile and update the installation folder,
specially if the folder path has changed
3) Install and configure the webserver
4) test it
5) Upgrade the system to new version
(https://wiki.duraspace.org/display/DSDOC5x/Upgrading+DSpace#UpgradingDSpace-BackupyourDSpace)
6) Test it

Done!

Well remembered, Luiz!
Specially the second point if you're dealing with a Git repository, because
it allows you to pull new versions of code without having to deal with code
conflicts. I've already used this method to do some customisation on xmlui
interface and it worked like a charm.

Re: [dspace-tech] Re: Solr Query of download and view.

2016-09-19 Thread Bruno Nocera Zanette

Hey! Glad it helped!!

As a said, you will have to parse the response to get this info. The field
of interest for you is "numFound".

For example, when i execute the query that i cited in the first message i
get the following response:

{
  "responseHeader":{
"status":0,
"QTime":2,
"params":{
  "q":"type:2 AND (id:68056753-e460-4f80-a08a-f8febfbd07f7)",
  "indent":"true",
  "fq":"statistics_type:[* TO *] AND statistics_type:view",
  "wt":"json"}},
  "response":{"numFound":4,"start":0,"docs":[
  {
"ip":"127.0.0.1",
"referrer":"http://localhost:8080/xmlui/";,
"dns":"localhost.",
"userAgent":"Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:48.0)
Gecko/20100101 Firefox/48.0",
"isBot":false,
"id":"68056753-e460-4f80-a08a-f8febfbd07f7",
"type":2,
"owningColl":["88c16bca-e689-4a71-b8f3-112191758c9a"],
"owningComm":["bc362b91-eb6d-4c95-bf2c-77dc2aeb20d4"],
"time":"2016-09-18T13:16:47.936Z",
"epersonid":"041c27dd-7c00-49c4-9192-55a3aed42994",
"statistics_type":"view",
"uid":"6d845ff5-2a9d-441f-a081-8190485f231c",
"_version_":1545826895597142016},
  {...}
}

In the beggining of the response there are the params that were used.
Then it comes the important part, that is the response itself. As any
other query, it says how many results were found and then the results
itself. So, if you are looking for some kind of statistic, the result
will be how many statistics were found.

How you will do it depends on the language you are using, but almost
definitely will be something like this (written on Ruby):
parsedResponse = JSON.parse(response)  # Parse the result
numFounds = parsedResponse["response"]["numFound"] # Access the
response field and then the attribute numFound.

And then you can iterate through the results if you want:
parsed_response["response"]["docs"].each do |r|
 puts r["ip"]
end

If the number of found results isn't the same as it appears on the
xmlui interface you have to revise the query, because it should be.

Re: [dspace-tech] change the query

2016-09-18 Thread Bruno Nocera Zanette

Dante,
You'll have to alter ItemResource's code on REST api:
https://github.com/DSpace/DSpace/blob/master/dspace-rest/src/main/java/org/dspace/rest/ItemsResource.java#L903
Specially the line 967. As i'm not a Java specialist i can't help you
besides that, but the idea is to return a hash like object (id,name) or an
array of ids, intead of an array of items.

The request must be in the format:
{"key":"dc.XXX.YYY", "value":"Query"}

Example:
curl -k -4  -H "accept: application/json" -H "Content-Type:
application/json" -X POST "
https://demo.dspace.org/rest/items/find-by-metadata-field"; -d
"{"key":"dc.title","value":"Test"}"

Re: [dspace-tech] REST Interface Sample App on Rails

2016-09-14 Thread Bruno Nocera Zanette

I've updated the app with several fixes, including Item edit, Table style
and adding buttons to create an object directly inside some other object.
The only thing that is still missing is adding/removing metadata fields to
item's form. For now there are only title and author fields for new items
and all existing metadata fields for old items. I'll try to implement this
feature this week.

Besides that, everything else are working. This includes Create/Edit/Remove
all kinds of objects, objects' table pagination, login/logout.

If you find any bug, please let me know.

Today i've fixed the authentication problem and i took the oportunity to
also implement a login form. It seems to be working fine. I had to make
some changes to the Gem and removed some code of Dspace5 auth, but later
i'll try to merge them into a single version.

Thanks, Ilja!
I took a look at the doc before but i didn't notice this change. I've
already updated the bash scripts to the new method and i'll update the Gem
later this week.

[dspace-tech] REST Interface Sample App on Rails

2016-09-06 Thread Bruno Nocera Zanette

Hey all!!

I've been writting, on my spare time, a REST interface sample app on Ruby
on Rails and it finally got to a point where i can show it to you. It is
fully based on "dspace-rest-client" ruby gem:

The link to the app is:
https://drcgem-sample-interface.herokuapp.com/

The code can be found here:
https://gitlab.c3sl.ufpr.br/bnzanette/DspaceRestSample
(P.s.: I plan to move it to github, but for now this is the only source.
It's completely safe and hosted by a research group on the University where
i study.).

I decided to keep it as simple as possible so that other people can use it
as basis for other apps. Like a "live documentation".

There are somethings that i still have to do to make it more usable, like
adding links to add collections/items/bitstreams on a
community/collection/item page, so that you don't need to always choose a
parent object when creating a new object. I also need to add a footer and
an "about page" to add "powered by..." infos and stuff like that.

However, for some reason, Dspace's REST login isn't working on
demo.dspace.org, so the app crashes everytime the buttons to save/edit are
clicked. On my tests on a 5.x version everything works fine.

Feel free to do whatever you want with it!! Hope you like it and find some
utility for it.
Cheers!!

[dspace-tech] Problem with login on REST API

2016-06-24 Thread Bruno Nocera Zanette

Hey!!

I'm trying to login on Dspace's REST API (v6/master) to test some things
but i can't. I've done it several times before and i can login on others
instances of Dspace (all v5.x), but it doesn't work on Dspace6. I've tried
on Demo DSpace and on a local instance (fresh install).

Something changed on login's request, on dspace 6? Or is it some bug or
system misconfig? Is it something about the new types of auth?

Thx!!
