Tim Dono= hue [9:00 AM] Reminder that in one hour (15UTC) is our weekly DevMtg in #dev-mtg . I hav= e a meeting just before that (starting now), but will see you in an hour. = Agenda at: https://wiki.duraspace.org/display/DSPACE/DevMtg+2018-09-05 Tim Donohue [10:00 AM] @here: It's DevMtg time. The agenda is listed above. Let's do a quick roll= call to see who is able to join discussion today. Terry Brady [10:00 AM] hello Alexander Sulfrian [10:00 AM] hi Mark Wood [10:01 AM] Hi. Tim Donohue [10:01 AM] Hello Terry, Alexander and Mark. Looks like we have a small quorum of folks= , welcome So, to start off the agenda with some notes from other meetings. I don't h= ave much to report out of DSpace 7 Dev meetings (work is progressing, but A= ug was slow. Sept looks like it should start to ramp up) But, we had our first DSpace 7 Entities WG meeting yesterday (several of yo= u were there) The notes/video from that meeting is at: https://wiki.duraspace.org/display= /DSPACE/2018-09-04+DSpace+7+Entities+WG+Meeting Pascal Becker [10:03 AM] Hi. has to excuse himself for at least parts of the meeting. will be here one e= yed for the other parts. Tim Donohue [10:04 AM] And as a reminder, even if you were unable to attend the DSpace 7 Entities = WG meeting, you are still welcome to provide feedback on the "early prototy= pe" of configurable entities If you wanted to give feedback, we ask that you review the "early prototype= " documentation and add inline comments/questions/concerns: https://docs.go= ogle.com/document/d/1wEmHirFzrY3qgGtRr2YBQwGOvH1IuTVGmxDIdnqvwxM/edit Those comments/questions/concerns will help drive conversation in the comin= g meetings...next meeting we'll concentrate more on the proposed Data Model= changes (The next DSpace 7 Entities WG meeting will be next Tues, Sept 11 at 15UTC) I think that's it for quick updates/notes from other meetings...any questio= ns/comments on any of that (or anything I forgot?) Ok, not hearing anything Moving along, DSpace 6.x -- no updates to speak of. However, DSpace 5.x has a topic (#3 on the agenda).... whehter we should co= nsider a 5.10 release in the near future I believe the main call for this is because the REST API was accidentally b= roken in 5.9. It was a small fix, but an important one to anyone using it = in 5.x Here's the fix/problem: https://github.com/DSpace/DSpace/pull/2197 Terry Brady [10:08 AM] REST was definitely broken. RDF might also have been broken. Tim Donohue [10:09 AM] Is RDF fixed yet? I hadn't seen any reports of RDF being broken in 5.9, ye= t Terry Brady [10:09 AM] If we do decide to expedite a release, it would be good to find folks who c= ould agree to validate each of the webapps. Let me find the other PR... Tim Donohue [10:10 AM] So, I'll say I'd approve pushing out a quick 5.10 -- I agree though that we= want to ensure we aren't immediately turning around and pushing out a 5.11= for other small issues. So, finding a list of the small issues to fix wou= ld be good Terry Brady [10:10 AM] https://github.com/DSpace/DSpace/pull/2104 Tim Donohue [10:10 AM] That said, I won't have time myself to push out 5.10 -- I'll help support i= t, but I'd need a different release manager/coordinator Terry Brady [10:10 AM] I think the wrong postgres jar made it into RDF. I'll be glad to take that on. I would just want to find someone familiar with Sword and with RDF to help = validate those webapps. Tim Donohue [10:11 AM] PR#2104 affected RDF? Oh, I didn't realize that. I thought it was just a = PostgreSQL library issue if you wanted to run DSpace 5.x + Java 7 Terry Brady [10:11 AM] I should be able to verify the others. Pascal Becker [10:11 AM] @terrywbrady We should setup a Docker image with a Triple Store to make it = easy to test RDF. Would you like to work with me on that? Terry Brady [10:12 AM] Sure @pbecker Pascal Becker [10:12 AM] Great. BTW I think dspace-rdf does not need Postrgres at all. But it=E2=80=99s bin= some time I developed that. Terry Brady [10:13 AM] If you ran 5x with Java7, any webapp that accessed that postgres jar would = not start. If RDF does not use postgres, I do not know if it would encount= er the error. It sounds like @pbecker and I should be able to validate the issue. @pbecker are you familiar with Sword? Mark Wood [10:14 AM] If dspace-rdf uses a Context then it is using the DBMS. Pascal Becker [10:14 AM] Not much. I would appreciate if someone else could take care for sword. Tim Donohue [10:14 AM] Ok, I was just trying to understand if PR #2104 *fixed* the issue. It soun= ds to me like it should be fixed, but needs further testing. Pascal Becker [10:15 AM] @mwood I=E2=80=99m not sure that it uses a context at all. It is basically = a proxy in front of the triple store. The data is converted into RDF as par= t of dspace-api. Tim Donohue [10:15 AM] And yes, it makes sense that Java 7 would cause all webapps to fail -- as, = prior to PR #2104 we were accidentally using a Java 8 Connector to Postgres= -- and Java 7 didn't work with it at all. So, @terrywbrady, if you are willing to act as 5.10 Release Coordinator, th= at'd be wonderful. It sounds like the latest `dspace-5_x` branch may alread= y have all the fixes we require (PR#2104 and PR#2197) So, it might just be a matter of testing that branch & cutting a releas= e Terry Brady [10:17 AM] Considering that we had 2 different POM dependency issues, I am curious to = to a minimal check of every webapp esp the less frequently used ones. Any = tips on testing Sword? and Swordv2? Tim Donohue [10:17 AM] We have sample commandline commands in both the SWORD and SWORDv2 docs that= can be used for simple tests...lemme find them Terry Brady [10:18 AM] That would be great to have. Thanks. Tim Donohue [10:18 AM] SWORDv1 submit: https://wiki.duraspace.org/display/DSDOC6x/SWORDv1+Server#S= WORDv1Server-DeposittoSWORDServer Terry Brady [10:18 AM] Keep this on the agenda. I will hope to find time over the next couple wee= ks. Tim Donohue [10:18 AM] SWORDv2 submit:https://wiki.duraspace.org/display/DSDOC6x/SWORDv2+Server#SW= ORDv2Server-DeposittoSWORDv2Server I linked to the 6.x docs there, but the commands are identical for 5.x Mark Wood [10:19 AM] LocalURIRedirectionServlet does indeed create a Context, which it needs to = resolve a Handle. Pablo Prieto [10:19 AM] Hi all. Excuse me for the late arrival. Tim Donohue [10:20 AM] There's a sample SWORD package (example.zip) that can be used for submissio= n tests at: https://github.com/DSpace/DSpace/tree/dspace-5_x/dspace-sword/e= xample Terry Brady [10:20 AM] Hi @Pablo Prieto Thanks. As a result of this we should also be able to generate some docume= ntation on running the RDF service with Docker. Tim Donohue [10:22 AM] That'd be great! Thanks again, @terrywbrady for being willing to coordinat= e this. One final thing...I think we should create a small 5.10 Release Status page= to track this work...something like https://wiki.duraspace.org/display/DSP= ACE/DSpace+Release+5.9+Status Terry Brady [10:23 AM] I will create one. Tim Donohue [10:23 AM] And I'll keep this on the agenda in coming weeks so we can check in on prog= ress Any last comments/questions here? (One obvious comment -- if anyone else listening in finds additional small = 5.x bugs, report them immediately please...and we can consider for 5.10) Pascal Becker [10:24 AM] @mwood thank you for taking a look into dspace-rdf. Do we have the same problem with DSpace 4? Tim Donohue [10:26 AM] 4.x did not receive the same backports at 5.x. So, I'm doubtful it was aff= ected -- but it's worth checking if any of these changes made it into 4.x Specifically, there were only two security fixes (both to JSPUI) that were = released in 4.9: https://wiki.duraspace.org/display/DSPACE/DSpace+Release+4= .9+Status No other bugs were backported Pascal Becker [10:28 AM] :+1: Tim Donohue [10:28 AM] So, that should mean 4.x is fine. Neither of these security fixes seems to= be the cause of these issues Ok, sounds like that topic is wrapped up then. We'll move along Terry Brady [10:30 AM] https://wiki.duraspace.org/display/DSPACE/DSpace+Release+5.10+Status Tim Donohue [10:30 AM] I left this on the agenda at #4.... I know we're still looking for more ide= as for future Dev Show & Tell meetings: https://wiki.duraspace.org/disp= lay/DSPACE/DSpace+Developer+Show+and+Tell+Meetings I'm not sure we have a topic for September. So, the question is...what wou= ld folks like to talk about? Should we have a September meeting? Is there= some other Dev discussion this could be used for? Pascal Becker [10:33 AM] Is it already the right time to dig deeper into the DSpace 7 architecture? I know that this is still moving, but I think it would be a chance to help = new people onboard. I=E2=80=99m thinking on some more techincal aspects. Example given: how will we encapsualte our authority layer into spring secu= rity, =E2=80=A6. Tim Donohue [10:35 AM] I'm not against the idea, but some of this is definitely a moving target. = The onboarding workshops from OR2018 are still the most "up to date" Pascal Becker [10:35 AM] And another idea: Would it be worth to have a Dev Show and Tell to discuss = if we could and should use Spring even more than we already do? Terry Brady [10:36 AM] @pbecker, that sounds like an architectural direction question... I recomme= nd that for a DSpace 7 meeting. Pascal Becker [10:36 AM] @tdonohue you can judge much better that me if it would be helpful and it c= ould help with the next sprint. @terrywbrady I=E2=80=99m not so much into spring. I don=E2=80=99t know how = others are. So the idea was to use this as a starting point. I was just a m= ore spontanious idea that came to my mind. Maybe you=E2=80=99re right and o= ther topics are better for the Dev show and tell. Terry Brady [10:37 AM] I love the idea of digging deeper into things like Spring or the authorizat= ion layer. If you could propose a topic and a potential speaker, I would be= happy to invite folks and coordinate the invite. Tim Donohue [10:38 AM] I think general developer Q&A / brainstorms are reasonable. I think the= problem is in finding a "speaker" (if we want this to be "show & tell"= )... Or we consider just turning this one into more of a brainstorming meet= ing? Mark Wood [10:38 AM] There's an old Jira issue about recognizing that Spring is our one and only= actual ServiceManager, cleaning out some complex un-needed code. Tim Donohue [10:39 AM] Running another DSpace 7 "workshop"/ training session might be difficult ri= ght now, as it takes away from our DSpace 7 dev resources (which we sorely = need to keep "on schedule"). I would love to have such a DSpace 7 training session in the future, I just= worry this is not the best time...and the training would be nearly identic= al to what was done at OR2018 Pascal Becker [10:40 AM] @tdonohue who is working on the spring-security for dspace 7? Couldn=E2=80= =99t that be a speaker for this specific topic? Tim Donohue [10:40 AM] Tom Desair (who recently got a new job) was the lead on spring-security for= DSpace 7 Pascal Becker [10:40 AM] @tdonohue it was just an idea. If you thing it is not the write time now, t= han postpone it. @tdonohue @tom_desair wants to stay active (of course with reduced time on = DSpace). Maybe it is worth asking him? Could be helpful to transfer the kno= wledge. Tim Donohue [10:41 AM] The spring-security stuff could be talked about more...but admittedly, we n= eed more folks to dive in here & chip in... Tom got the ball rolling, b= ut it's not entirely "done" yet. Terry Brady [10:41 AM] If one of us wants to lead the discussion from the perspective "here are my= questions about Spring" that could also be a good place to start a convers= ation. Mark Wood [10:42 AM] Hardy Pottinger was interested in consolidating authNZ in something like Sp= ring Security. I don't know how much time he has for that right now. Tim Donohue [10:43 AM] If someone wants to ask @tom_desair, I'm OK with it. Not sure whether he'll= have free time for it yet...but it's worth asking. It sounds like we don't have a firm idea here. I know I'm not going to be a= ble to answer all the questions on Spring that folks have, but I'm willing = to help with a Developer Q&A session of sorts (if folks come with quest= ions) Terry Brady [10:46 AM] I will update the Show and Tell Wiki Page with that as a possible future to= pic. Tim Donohue [10:47 AM] I think the reality on DSpace 7 specific topics here is that we are trying = to present on a moving target (and I worry anything we present on could be = outdated before end of year) So, discussion / Q&A on DSpace 7 is perfectly fine to me. But, formal = training/presentations are maybe not easy right now Mark Wood [10:48 AM] We may hope that the target will slow down toward the end of the year, so m= aybe later would be an appropriate time for presenting on it as the code se= ttles down. Terry Brady [10:48 AM] We can put the meetings on hold until we have a compelling topic. Tim Donohue [10:48 AM] But, now that I type that...maybe we could hold a session on "Ask us about = DSpace 7!" ? Come get your questions answered on the future of DSpace (edit= ed) Pascal Becker [10:49 AM] When I started with DSpace, I had problems to understand the structure of t= he DSpace API. Would it make sense to offer some introduction to the DSpace= API? I was surprised last time how many people that I didn=E2=80=99t knew = before joined the meeting about Docker. What does other think here could th= at be another topic? Some kind of introduction for new developers=E2=80=A6. Terry Brady [10:51 AM] I like the idea of a general Q&A for new developers/contributors. I could post a question to the email lists and slack channels to compile qu= estions. Tim Donohue [10:52 AM] I'd sign up for any sort of Q&A. I'm happy to answer any questions tha= t developers have. I wouldn't come with any formal "presentation" or "show = & tell", but I'll gladly hang out for 60-90mins answering questions (or= pointing people to resources to learn more) Mark Wood [10:52 AM] Topic for next year, after DSpace 7 releases: when I look at the UI, how t= o figure out where a feature comes from and where to build a new feature to= have it appear *there*. That is the thing that consumes 90% of the time I spend on XMLUI. Tim Donohue [10:53 AM] @mwood: Yes, I think that's the goal for early next year & at OR2019. = To actually have training on customizing the new DSpace UI. We don't have = that yet, but will Terry Brady [10:54 AM] I am capturing ideas here: https://wiki.duraspace.org/display/DSPACE/DSpace= +Developer+Show+and+Tell+Meetings#DSpaceDeveloperShowandTellMeetings-WishLi= stofTopics Tim Donohue [10:55 AM] Ok, so lots of brainstorms here. It doesn't sound to me like a formal decis= ion. But, I'm willing to be involved with a Q&A for developers or a Q&= amp;A on DSpace 7 (or both) at some point in the future. Pascal Becker [10:55 AM] I think we could also bring up something like: the states of an item, how d= o I bring a new Item into DSpace, what is it with the DAOs, the Services an= d the Impls. I have to run now, but we should continue on this. bye everyone! Pablo Prieto [10:55 AM] Bye Terry Brady [10:55 AM] Have a good week @pbecker. I will be in touch about RDF. Bye @Pablo Prieto (edited) Tim Donohue [10:56 AM] We are nearing the end of the meeting time...I don't know that we have many= more topics though I noted under topic #5 that I'm still looking at crediting folks for code r= eviews, etc (via GitHub GraphQL) Pablo Prieto [10:56 AM] I have a small topic. I don't know if this is the place. Tim Donohue [10:56 AM] You can look at my notes there for more details though @Pablo Prieto: sure, go ahead with your small topic Pablo Prieto [10:57 AM] I don't know If this is implemented. But Is there a way to do the community= -subcommunity filliation other than the cli? Alexander Sulfrian [10:58 AM] I don't think that's currently possible. Tim Donohue [10:58 AM] You mean moving/restructuring Community/Subcommunity hierarchy? No, that's= not in the UIs in DSpace 6 Pablo Prieto [11:00 AM] This came up because as some more security-oriented entities use DSpace, th= eir IT deparments restrict access to the server shell, so Dspace admins are= left to either request support tickets or just create another community. I don't know your considerations on this, but I think we should figure out = a way to do that through the UI Tim Donohue [11:00 AM] It's not yet in the DSpace 7 REST API either...but, it likely could be adde= d at that layer (which would allow folks to create a UI screen for it in DS= pace 7) Terry Brady [11:01 AM] @Pablo Prieto we have built a companion set of tools for our DSpace (writte= n in PHP) that provide web page access to various CLI functions. Pablo Prieto [11:01 AM] But that would mean adding php capabilites to the server? IT guys will go crazy on that. Terry Brady [11:01 AM] I would not recommend implementing in PHP... I am just saying that we had t= he same need. Pablo Prieto [11:01 AM] Maybe we could add this to the existing REST-API Tim Donohue [11:02 AM] To me, it seems like this should be possible from the UI. But, we've just = never had anyone add it in. It seems like it shouldn't be too bad to add t= o the DSpace 7 REST API .. since the underlying Java API already exists Pablo Prieto [11:02 AM] I you can be patient enough, and this seems usable for other,s, I could tak= e a look into it. So that would be for DS7+ Tim Donohue [11:04 AM] Yes, I'd propose new features like this be aimed more for DSpace 7. We ten= d to encourage new features only for upcoming (unreleased) versions... so, = 6.x won't get any more new features -- just bug fixes, security fixes &= minor improvements Terry Brady [11:04 AM] If you are curious, here is an overview of what we have implemented. https= ://github.com/Georgetown-University-Libraries/batch-tools All of this functionality would be nice to migrate to REST. Even better if= it could migrate to a curation task that could be invoked from either REST= or CLI. Tim Donohue [11:05 AM] (And for the 7.x release, it's very important to not add more major feature= s to 6.x, as that makes 7.x a moving target -- anything we add to 6.x must = also be added to 7.x) I'm realizing we are over time here (5 past the hour) So, I'm going to go ahead and wrap up today's meeting. Discussion is welco= me to continue, but we won't call any more agenda items. Mark Wood [11:06 AM] However, if the feature is needed soon, 6.x might make a good prototyping p= latform. I don't think that porting to 7 would be terribly difficult. Pablo Prieto [11:06 AM] OK, I'll look into that. I also have some other ideas. I'll wrap them in a = wiki page and report back. Tim Donohue [11:06 AM] Yes, it's perfectly fine to develop against 6.x locally & use it locall= y. We just won't merge it into the public 6.x branch Terry Brady [11:07 AM] The REST interfaces are so different between 6 and 7 so a solution would no= t port to the new API. Mark Wood [11:07 AM] The concepts will be similar, though. Tim Donohue [11:08 AM] I've unfortunately got to run...so, the meeting is "complete" for today. B= ut, as noted, feel free to continue discussion (and I'll copy it into the n= otes). Thanks all! Mark Wood [11:09 AM] And there is a lot to work out, concerning how the feature will be presente= d to the user. That will have to be translated to the way things are done = in the Angular UI, but again you don't lose *everything*. It's a question of whether having the feature without waiting for 7 is wort= h the effort of porting later. Pablo Prieto [11:10 AM] Both rest APIs call the underlying dspace-api, so the approach might be sim= ilar. Whats the ETA for DSpace 7? Terry Brady [11:12 AM] As long as the migration risk is understood, it is never a bad idea to expe= riment. I hope you all have a good week. Mark Wood [11:13 AM] I think that the current estimate is "early 2019." Pablo Prieto [11:13 AM] Thank you @terrywbrady. The same for you! Oh, thats not too far. Tim Donohue [11:14 AM] Yes, goals for DSpace 7 are beta by end of 2018, and final release by early= 2019. Those are still estimates, but Steering Group has made it clear tha= t they want us to get 7.x out as soon as possible (so we are trying to hit = those goals) Pablo Prieto [11:14 AM] Ok Thanks! Terry Brady [11:16 AM] What is the LNI service? I am creating a grid for the webapps in DSpace 5.= 9 and I had forgotten that exists. Tim Donohue [11:17 AM] https://wiki.duraspace.org/display/DSPACE/LightweightNetworkInterface (Depr= ecated in 5.x, removed in 6.x) Mark Wood [11:17 AM] It's a remote submission service, like SWORD except only DSpace has it. It= has very few users, if any are still left. Tim Donohue [11:17 AM] It was never known to be used by *anyone*. We contacted the community abou= t deprecation/removal and heard nothing Mark Wood [11:18 AM] Wasn't there one site in the UK that was using it? I think they planned to= move off it, though. Tim Donohue [11:20 AM] Edinburgh, possibly...they used it at one time a long time ago. It was bui= lt way before SWORD, and I'm not convinced it was ever really used other th= an by Edinburgh & Harvard (who built it). In any case, if it "builds", I wouldn't worry about LNI until someone compl= ains (And I've never seen a complaint about LNI since I've been at DuraSpace...w= hich is nearing 10 years) Terry Brady [11:21 AM] For 5.10, I am going to start by filling in the following grid: https://wik= i.duraspace.org/display/DSPACE/DSpace+Release+5.10+Status#DSpaceRelease5.10= Status-WebappStatus Mark Wood [11:22 AM] That grid looks like a good starting point. Tim Donohue [11:24 AM] @terrywbrady: seems like a good starting point. Just a minor clarification= regarding DS-3938... Pretty sure 5.9 works fine (except REST API) if you a= re using Java 8. But, if you use Java 7, then issues will arise. So, whic= h version of Java you are using with 5.9 may be a factor here Terry Brady [11:24 AM] Thanks. That will be useful to note. Tim Donohue [11:25 AM] Since 5.x documents that it works with Java 7, we should test it with Java = 7 to be sure. But, Java 7 is EOL (for some time), so ideally, most folks s= hould be upgraded to Java 8 these days.
