Re: [Blacklight-development] need help in installing Blacklight
Yongming Wang
Now I came to another problem.
When I come to step 3 to Install blacklight using Devise for user authentication: the first part is OK ($gem install devise) after solving some directory write permission issue.
but when I do the second part:
$rails generate blacklight --devise
The screen threw me a rails usage page like the following:
rails new App-Path (Option)
......
What's going on here?
Thanks very much for your help.

I have a bigger issue down the road when I look at the Quickstart instruction. The step 5 requires to install solr.
My physical server has VuFind on it which also uses Solr.
My question is: can these two products, or their Solr engines, co-exist on the same machine. What is my best strategy to implement step 5 as it gives three options for the Solr solution.
Thank you very much.
James Stuart
If your other solr is not on port 8983, then just follow the
blacklight jetty instructions. They'll be on different ports and
that's fine.
If it's already on 8983, then you can change the port of the
blacklight jetty installation (google change port jetty). Note, you'll
need to change config/solr.yml as well.
More permanently, solr can be set up in a multi-core mode, which
allows you to run multiple cores under the same solr server.
Finally, blacklight can be configured to read almost any existing solr
index, but I'd recommend not starting with that.

Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.

How many different version of rails do you have installed (paste or gist a 'gem list')? I think this ended up being a bundler/rvm issue for me, but I don't know how that would translate to ubuntu.

A quick question regarding step 5 in Quickstart instruction:
After I did "$rails generate blacklight:jetty, do I still need to do "$rails generate blacklight:solr_conf path/to/output/directory/?
Thanks,
James Stuart
Jessie Keck
That 2nd line (w/ path/to/output/direcotry) is just telling you how to generate Blacklight's solr configuration to a solr instance outside of Blacklight (e.g. if you had a pre-existing solr instance and were not using the what that comes w/ Blacklight).
Just out of curiosity did you resolve the error you were running into before w/ the rails generate command?

So happy. Thanks for all your help.

We are a library consortium in New Jersey. We want to evaluate Blacklight for our next generation discovery tool. A few days ago I installed Blacklight onto our testing server, imported 50,000 plus sample marc records from multiple libraries.
I have a couple of questions regarding the consortia feature of Blacklight:
1. How do we search and display records for different libraries?
2. Does Blacklight support resource sharing within the consortium?
I looked at the Blacklight installation list and didn't see any consortium name. If any of you know of such case, please let me know.
Thank you very much.

If 1) is: How do we ingest multiple library's records into one index,
you will be able to just ingest multiple marc files. You can add tags
or identifying fields to denote which source they came from, and then
display either all the records, or libraries one at a time.
I'm not sure what 2) means. Could you elaborate a bit more?

James is right about this. In short, you most likely will need to add
additional fields that denote the source, and you may want to add
links back to the original OPACs.
I did this to build a prototype for a consulting project, and ended up
using SolrMarc's custom BeanShell indexing scripts quite a bit to
insert custom values.

Hi Yongming,
The University of Wisconsin-Madison is using Blacklight in a consortial mode:
http://forward.library.wisconsin.edu/
http://forward.library.wisconsin.edu/home/choose_campus
From our perspective, Blacklight is a general resource discovery system, whether it is used for an interface to digital collections or a library catalog. BL, in a sense, is data agnostic and very flexible in this way, but that means that the system does not have any consortial functionality natively. We have done a lot of local customization to develop BL to be used for all 14 campuses in the UW System:
* Designed our index with a schools facet with values like "UW-Madison" or "UW-Milwaukee"
As suggested by Justin, this allows us to scope searches to a single campus.
* Rewrote the BL views to display different data based on the default campus for a user
Compare a search at UW-Madison:
http://forward.library.wisconsin.edu/catalog?q=wittgenstein&qt=search&local=true&school_code=WU
to the same thing across the entire UW System:
http://forward.library.wisconsin.edu/catalog?&local=false&per_page=10&q=wittgenstein&qt=search&school_code=WU
Compare a single record view for a Madison-only e-resource:
http://forward.library.wisconsin.edu/catalog/ocm53363703?school_code=WU
to the view for a UW-Milwaukee patron:
http://forward.library.wisconsin.edu/catalog/ocm53363703?school_code=WMUW
* Wrote code to user our ILS Vendor's API for UW System borrowing
Because consortial borrowing is critically important, we have written code to work with our ILS API to make sure that we can place requests for book delivery from one campus to another.

I really enjoyed following this email thread, and I hope you'll continue to share your process with us. It is so helpful to understand what new adopters go through and understanding what it's like for you can really influence the direction of the project and its documentation and installation process.
Once you get some content indexed I hope you'll share with us what you made.
Cheers,

I studied both Wisconsin's and Stanford's Blacklight implementations. Both are very impressive!
It seems to me that the two implementations took different approaches. Am I right in saying that Wisconsin has multiple ILS across the system and Stanford has one ILS only. The Location facet at Stanford is very eye-catching. And the request feature ("Paging for Delivery" link) is what I meant by saying "Resource Sharing". But can you do that in the multi-ILS environment which is our case? -- not only we have multiple ILS but also they are from different vendors.
My next question (I don't know if it is right question to ask): I'd also like to know that in Wisconsin's case, have you built a shared, centralized bib database to support the Solr search engine? If not, how do you update your solr index?
I can see that in both implementations you have to add additional Marc tag/fields (852 in Wisconsin's case and 999 for Stanford) to display the holding information. Does that require heavy customization work? I just want to get a sense of how much work and what kind of skills needed to make this happens.
Thank you so much, again, for all you inputs and guidance.

Subject: Re: [Blacklight-development] Blacklight in consortia setting?
Yongming,
University of Wisconsin's Forward system is the best example of a consortial Blacklight instance that I'm aware of.
http://forward.library.wisconsin.edu/
You can search the combined records of all UW schools, or limit your search to a particular campus. If you want to add a facet by library location (something that I don't see in Forward's current views), you could do as James and Justin suggest. SearchWorks ( http://searchworks.stanford.edu ) has an example of this where we provide searchers with the ability to limit their searches or just browse by location of library on campus.
By resource sharing, if you mean ILL or cross-library borrowing, I think this will be more of a function of your underlying ILS(es) than Blacklight as a discovery layer, but BL can certainly support this by letting you integrate ILL or paging / request forms into your application. We've done this at Stanford as well (as have several other schools) by building simple web forms and a little bit of logic that interact with the underlying ILS calls for paging items / putting a hold on them / etc. We're happy to share this code if you (or anyone else) is interested. Our ILS is SirsiDynix Symphony.
Hope this helps,
- Tom

this is correct - Stanford's SearchWorks MARC data is from our sirsi Symphony installation

The Paging for Delivery is done with a locally grown application that interfaces with Symphony as needed. There is no barrier to having more than one such application, one for each ILS.

The Sirsi API provided a way to get item information in 999 fields. UVa, which is also a Sirsi site, does the same thing. In both our case and UVa's case, the local gurus for sirsi are separate people from the ones who index the marc data into Solr for blacklight.

Robert Haschart
Here at the University of Virginia (similar to Stanford) the holdings information is appended to the MARC records in 999 fields. This is done by the ILS system as it dumps out the MARC records. The info is in that field merely because that is where the SirsiDynix Symphony software decides to put it. In our case the holdings info is directly appended to the records as they are out, other systems write out the holdings info into a separate file, or as subsequent MARC records only containing the holdings info in the same record stream.
Once you know how the ILS system (or systems) that you will have to work with provides the holdings information, it is a relatively simple matter to create a SolrMarc indexing specification to extract that information and write it to the Solr index. Depending on where/how the info you want is stored in the holdings info, the skills needed extract it can be as simple as editing a couple of properties files, or it might require some java-like scripting, or small bits of custom java code.

As the primary developer on SolrMarc, I'm interested in the reasons for developing custom code to handle the updating and indexing of your records. There are tools built into SolrMarc that seem that they would do most or all of what you are currently doing.
The updating process here at UVA is similar in many respects to what you do (except for the merging records with a common OCLC number) and nearly all of it is done via the scripts that are included as a part of the SolrMarc distribution.
